Isaac: A Funny Foundation (Genesis 21:1-21)

Genesis 21 recounts the fulfillment of God’s long-awaited promise to Abraham and Sarah—the birth of Isaac. This chapter centers on God’s faithfulness, the nature of grace, and the surprising ways God accomplishes His purposes.

The chapter opens with the Lord visiting Sarah, just as He had promised (v. 1). At the age of 90, Sarah gives birth to Isaac—a name meaning “laughter”—as a testament to the joy that comes when God’s promises are fulfilled, even in the face of human cynicism.

Isaac shows the Lord’s redemption: God moves his people from cynical laughter to joyful celebratory laughter.  God’s promises don’t operate on our timeline; they operate on His. Isaac’s arrival reminds us that waiting on God is not wasted time but formative time—teaching trust in His sovereignty.

Isaac’s arrival contrasts sharply with Ishmael’s, Abraham’s son through Hagar. Ishmael represents human effort—Abraham and Sarah’s attempt to secure God’s promise through their plans. Isaac, however, is entirely the result of divine grace, showing that God’s blessings come as gifts, not as something we can earn or achieve.

Isaac shows the impossibility of the Christmas promise.  The thought of the Lord establishing his promise through death seems absurd.  However, Abraham and Sarah testify that the Lord establishes life through death because the Lord knows the depth of sin, and what it will take to overcome it.  Isaac sets the joyful foundation, but Christ is the one who definitively establishes the foundation by fulfilling God’s promise.

Comforted in One True Savior (LD 11; 1 Cor. 1:10-17)

Paul addresses a fractured church, divided into factions based on allegiance to specific leaders—Paul, Apollos, Cephas, or even Christ in a tribalistic sense. These divisions reveal the human tendency to seek identity and superiority in secondary things, even in the church. Paul responds by re-centering their focus on Christ alone, emphasizing that their unity and salvation are rooted not in the messengers, but in the message of the cross.

Human hearts naturally turn good things, like church leaders or even the gospel, into ultimate things that ironically look away from Christ. We are those who create idols that divide rather than finding significance in Christ. But Paul dismantles these divisions by reminding the Corinthians of the gospel’s leveling power: none of them were baptized into Paul or Apollos—they were baptized into Christ. The cross is not just the means of salvation; it’s the ultimate unifier, declaring that all believers are equally in need of grace.

The key takeaway is that the gospel creates a new identity transcending tribalism. In Christ, there’s no room for boasting in human leaders or factions because everything we have is a gift. This passage challenges us to examine where we are tempted to find our worth outside of Jesus and invites us to center our hearts and community on the One who unites us all.

Christmas' Foundation (Genesis 4:1-26)

Genesis 4 tells the story of life after the fall, revealing the deepening impact of sin and the hope of God’s redemptive plan. After Cain murders Abel in a tragic display of jealousy and defiance against God, humanity seems to be spiraling further into brokenness. Cain’s descendants establish cities, culture, and technology, but their achievements are tainted by arrogance and violence, as seen in Lamech’s boastful declaration of vengeance.

However, the chapter ends with a glimmer of hope. Adam and Eve have another son, Seth, whom Eve sees as God’s provision to continue His promise. Seth represents a new beginning and a fresh line through which God’s purposes will unfold. The text notes that during Seth’s time, “people began to call upon the name of the Lord.” This marks a turning point—amid the darkness, there is a remnant seeking God.

Seth, foundation, is God’s provision to set world history back on course. Where sin increases, God’s grace abounds more. The contrast between Cain’s line and Seth’s reminds us that even Lamech claiming god like power cannot thwart God’s plan. Through Seth’s descendants, we see the beginning of a faithful community—a foreshadowing of the ultimate Redeemer who would come to reverse the curse and establish a new humanity. Seth reminds us that in the midst of the world’s fallen and broken condition that God is working his redemption.

Comforted by Providence (LD 10; Acts 17:22-31)

In Acts 17:22–31, Paul addresses the philosophers in Athens, presenting the gospel, and calling them to see that they do not market god.  It is God who continues to uphold this creation whether we affirm it or not.

Paul begins by acknowledging the Athenians’ religiosity, even pointing to their altar “to an unknown god.” He uses their cultural and spiritual hunger as a starting point to reveal the true God — not a distant deity but the Creator who is near, sustaining all life.  Paul calls them to account for the fact that they do not discover and promote the gods but that there is one God who sustains all things.

Paul then calls them to repentance, announcing that this God has revealed himself in Christ. Jesus’ resurrection is proof that God will judge the world through him.

The resurrection isn’t just evidence of God’s power; it’s the assurance of his love and the hope of renewal for all creation.

Enlightning Sign of Jonah (Luke 11:29-36)

The crowd is seeking signs, challenging their demand for proof, but Christ says they will receive the “sign of Jonah.” Jonah was the sign to Ninevah so Christ is the sign for the current generation.

Then Jesus shifts to a metaphor of light and vision. The problem isn’t the light (the gospel) but the eye (our spiritual perception). If our “eye” is healthy, we’ll see clearly and live in the light. If not, we’re plunged into darkness.

So, we are not to demand signs but to see the Gospel as the sufficient light pointing us to Christ. We are to have a singular focus on the kingdom. As we are focused on the Lord’s kingdom, his light will continue to conform. Ultimately, it is the call to give ourselves to the Spirit, the sole source of light and life.

The Parable of the Vineyard (Matthew 20:1-16)

We welcome Mr. Roy Kim to our pulpit while Pastor Paul Lindemulder enjoys a week off.

In Matthew 20:1-16, Jesus tells the parable of the workers in the vineyard.

This parable challenges our sense of fairness and exposes the radical nature of God’s grace. A vineyard owner hires workers at different times throughout the day, yet pays them all the same wage. Those hired first grumble, feeling cheated, but the owner reminds them that he gave them exactly what he promised.

God’s grace is unearned and generous—It’s not based on merit or how long we’ve worked. Those who arrive late (like the thief on the cross) receive the same reward as lifelong believers because salvation is a gift, not a paycheck.

Our pride blinds us to grace—The first workers represent those who feel entitled to more because of their perceived efforts. Their complaint shows a heart that values comparison and fairness over gratitude.

Ultimately, this parable flips human values upside down. It invites us to rejoice in the generosity of God, rather than resent it, because none of us deserves his grace in the first place.

Fortified from Satan (Luke 11:14-28)

Jesus heals a man who was mute due to demonic possession, sparking amazement among the crowd. However, some accuse Him of using demonic power (Beelzebul) to cast out demons, while others demand a sign from heaven to prove His authority. Jesus responds with powerful logic, exposing the absurdity of their claim—why would Satan work against himself? Instead, Jesus declares that His work is evidence of God’s kingdom breaking in.

He warns that neutrality is not an option; those who are not with Him are against Him. He further cautions that simply ridding oneself of evil without filling the void with God leads to greater vulnerability. A clean but empty “house” is an open invitation for even worse spiritual oppression. Finally, when a woman in the crowd praises Jesus’ mother for giving Him birth, He redirects the focus, saying that true blessedness comes from hearing and obeying God’s Word.

This passage reveals the radical claim of Jesus’ authority and the decisive nature of following Him. It warns against the dangers of superficial spiritual change—reformation without the Lord’s transformation. Jesus doesn’t just aim to remove evil; He wants to renovate and regenerate with the presence and power of God.

Comforted by Abba (LD 8; Galatians 4:1-7)

In Galatians 4:1-7, Paul explains that believers in Christ are no longer like slaves with no real exercise of the inheritance.  It is in Christ that we are children of God through faith. We are no longer under the tutor who would teach us to be adults and function at some point as an adult.

With Christ’s coming, however, believers are redeemed from this bondage. Through Jesus’ sacrifice, we are not only set free as adults walking in the Spirit but also adopted into God’s family. This adoption allows them to call God “Abba, Father,” a deeply personal and intimate term that conveys closeness.  God is not a Roman Father who is harsh and unpredictable.  Rather, he is a Father who shepherds his children desiring to see them grow in him.

The use of “Abba, Father” reflects a significant shift from a relationship based on law and obligation to one based on grace and family.  It changes our motivation: we obey not out of fear but love and gratitude. With the Spirit within us, we can confidently approach God, not to earn favor but because we are already fully embraced as His children. This adoption and inheritance change everything, grounding our identity and security in God’s love rather than our performance.

Our Prayer (Luke 11:1-13)

Jesus’s disciples want to learn how to pray from their teacher. Jesus teaches them to pray to the father who places our absolute reliance on our heavenly father as citizens of his kingdom.

Jesus then shares a parable about a persistent friend. In this story, a man goes to a friend at midnight to ask for bread. At first, the friend is reluctant, but because of the man’s persistence, he eventually gives him what he needs. This parable illustrates the importance of persistence in prayer.

Jesus further encourages His disciples to “ask, seek, and knock,” promising that those who do so will receive answers. He emphasizes God’s desire to give good gifts. If fallen fathers know what is good for their children how much more our creator and redeemer? Ultimately, the greatest gift is the new birth, the entrance into the new family, and calling upon our heavenly father as Abba.

Comforting Assurance (Ephesians 2:1-10)

Ephesians 2:1-10 highlights the transformative power of God’s grace in the lives of believers. Historically because of Adam we are dead, living in sin and separated from God (verses 1-3). However, in verses 4-5, God takes the iniative by his mercy and love making us alive together with Christ.  His resurrection is not just overcoming our physical death, but moves us from children of wrath to children of God.

In verse 8-10, Paul makes it clear that salvation is a gift from God, not something earned by works. He states that we are saved through faith, and even faith itself is a gift from God. This means no one can boast about their salvation, because it is solely by God’s grace, not by human effort.  We only live out the gospel by the Lord’s power.

What Sort of Redeemer? (Genesis 3; LD 6)

Genesis 3 records the fall into sin. This is a tragic day when Satan enters the garden, challenging the Lord’s word. Eve is tempted, and Adam fails to defend the Garden Sanctuary. They eat of the tree of the knowledge of good and evil only to discover that death is separation from their communion and fellowship with God. Adam and Eve realize their nakedness, and they are ashamed, contrasted to the Lord’s creation when they were naked and unashamed. Now, they do not want to be vulnerable before the living God. Their fellowship is instantly broken. This act of disobedience brings sin and death into the world, altering humanity’s relationship with God.

God pronounces consequences on the serpent, the woman, and the man. Speaking to the serpent, God says, “I will put enmity between you and the woman, and between your offspring and hers; he will crush your head, and you will crush his heel” (Genesis 3:15). Humanity will be divided into two lines. There is the seed of the woman represented by the Messiah. Adam defected to the Satanic army. The Lord will rise and triumph over the Satanic Army as some of the human race will be the Lord’s seed, and some will be left on their course as Satan’s seed.

The Lord sets up a guarding angel with a flaming sword that administers eternal death. Anyone who gains access to the tree will be cut off. The Lord provides cover for Adam and Eve, symbolizing the first sacrifice. The Lord will pass through the sword as the God/Man. He will take the eternal punishment that man cannot endure. The first gospel is proclaimed in paradise as Adam and Eve are pushed out of the garden sanctuary. Jesus Christ will enter history, live a perfect life to consecrate his people, endure eternal punishment, and rise in victory to live in the heavenly temple as our eternal priest.

Applying Active Listening with Mary and Martha (Luke 10:38-42)

In Luke 10:38-42, Jesus enters a village, and Martha invites Jesus into her home. She is going to host Jesus with her sister, Mary. Martha is busy preparing and serving while Mary sits at Jesus’ feet, listening to his teaching. Frustrated, Martha tells Jesus to make Mary help her. However, Jesus gently tells Martha that while she is worried about many things, “only one thing is necessary.” He explains that Mary has chosen the “better part” by focusing on his teaching, something that won’t be taken from her.

Jesus clarifies that service in our strength is not service to God. One has to start in the renewing work of the Spirit, doing these works in the power of faith. Martha is simply doing and not hearing.

Are All Saved in Christ? (Romans 5:12-21; LD 4)

In Romans 5:12-21, Paul explains how sin entered the world through our representative Adam, leading to death for all humanity. He contrasts Adam’s disobedience with Christ’s obedience. While sin and death spread through one man’s failure, God’s grace and the gift of righteousness come through Jesus.

Paul emphasizes that just as death reigned through Adam, grace reigns through Christ, offering eternal life to those who believe. Paul points out that all in Christ are saved, and all in Adam are condemned. This is not a universal salvation but a consolation that Christ’s work overcomes Adam’s fall for all who are in Christ Jesus.

How To Be Saved? (Luke 10:21-37)

Jesus rejoices in the revelation of truth to the humble and contrasts it with the wise. By God's grace, anyone is considered among the humble.

Christ then engages with a lawyer who asks, “Teacher, what shall I do to inherit eternal life?” The man summarizes God’s law. The lawyer, seeking to justify himself, asks, “Who is my neighbor?”

In response, Jesus tells the parable of the Good Samaritan. In the story, a man is attacked and left for dead. A priest and a Levite pass by without helping, but a Samaritan considered an outsider, stops to aid the man, showing compassion. Jesus concludes by asking which of the three acted as a neighbor, teaching that the kingdom boundaries are beyond Israel and transcend social boundaries. We are not to ask who is my neighbor, but to ask, “How can I be a better neighbor?”

God’s Temporary Truce (Genesis 8:20-9:17; LD 3)

Genesis 8:20–9:17 Noah the soother gives off a soothing aroma after the ark rests (noahs) on the top of Mount Ararat. builds an altar and offers sacrifices, which pleases God. God delivers Noah, and his family, through the flood onto a new creation. It is the precedent and picture of God shepherding his church from this world to the glorified creation.

God blesses Noah and his sons, commanding them to be fruitful, multiply, and fill the earth. He allows them to eat animals but forbids blood, symbolizing life. God also declares that human life is sacred, stating that anyone who sheds human blood will be held accountable. God will restrain sin so the gospel can go forth.

The sign of the rainbow is a reminder that the Lord has put down his war bow. He will preserve this creation through seedtime and harvest and the various seasons. However, he will pick up that war bow on the final Har Maggeden (mountain of judgment) day and put down the rebellion. This narrative teaches that one wants to be part of the ark community. One wants to be part of the community that has moved through death and now possesses everlasting life in Christ Jesus. Yes, man has a season to continue to rebel, but man’s rebellion will not spiral out of control. However, the Lord will squash man's rebellion once and for all. The Lord is teaching that he will shepherd his people into the new heavens and earth.

Kingdom Harvesters (Luke 10:1-20)

Jesus sends out 72 disciples in pairs to bear two-fold witness to announce his coming. He gives them specific instructions, telling them to rely on the hospitality of those they meet, heal the sick, and proclaim that the kingdom of God has come near. Their reception in the village determines the village’s reception of the messengers.

They are lambs/sheep among wolves. This kingdom is not here in its full glory as we see Israel experiencing rebellion. The New Testament letters record wolves in various congregations. The kingdom is here with Christ, spiritually realized, but not in full glory.

When the disciples return, they are filled with joy, reporting that even demons submitted to them in Jesus’ name. Jesus responds by affirming their authority over the power of the enemy, but he reminds them that their true joy should come from knowing that their names are written in heaven as sons of peace identified in a new Messianic family.

Initiating the Exodus (Luke 9:51-62)

In Luke 9:51-62, Jesus resolutely sets out for Jerusalem, knowing His mission involves suffering and sacrifice. On the way, a Samaritan village rejects Him, but He rebukes His disciples for wanting to call down judgment on them. As they continue, different people express a desire to follow Jesus, but He warns them that following Him demands radical commitment. He tells one that the Son of Man has no place to rest, indicating the hardship of discipleship. To others, He stresses that nothing, not even family obligations or looking back at past life, should take precedence over following Him.

This passage teaches that Christ’s exodus is laser focus on the heavenly Jerusalem.  The values and priorities of this age all submit to the the goal of the heavenly Vision of Peace (Jerusalem).

What is Your Comfort? (Titus 2:11-15; LD 1)

Paul writes this letter to Titus in Crete. Paul encourages Titus to teach believers to renounce ungodliness and worldly passions and to live self-controlled, upright, and godly lives in the present age. Believers are encouraged to see themselves stationed between two epiphanies, that is two events where God has manifested himself. On the one hand God redeems an international people by confirming his promises in Christ which is the first epiphany. We are called to look forward to the blessed hope of Jesus Christ’s return, second epiphany, who gave Himself to redeem and purify a people for His own possession, eager to do good works. We live between these two Christ events knowing that our Lord continues to purify and work in his people.

God’s Ark People (1 Peter 3:18-22)

In this passage, Peter highlights the profound work of Christ in His suffering and victory, showing how the gospel reshapes everything—even our understanding of baptism. Jesus, the perfectly righteous one, suffered and died for the unrighteous to bring us to God, demonstrating that salvation is entirely a work of grace. He didn't just die; He was resurrected, triumphing over all spiritual forces.

Peter then connects this victory to the story of Noah, using the flood as a powerful analogy for baptism. Just as Noah and his family were saved through the waters of the flood—not by their own efforts but by trusting in God’s provision—the waters of baptism now symbolize how we are saved, not by physical cleansing, but by the resurrection of Christ after descending to death. Baptism is not a mere ritual; it’s an outward sign of an inward grace, a pledge of a cleansed conscience made possible only through Jesus’ resurrection.

Increase Our Faith (BC 24; Luke 17:5-10)

Mr. Sen Zorilla exhorts us this evening from Luke 17:5-10.

The disciples ask Jesus to increase their faith. In response, Jesus tells them that even a small amount of faith, as small as a mustard seed, can achieve great things, such as uprooting a mulberry tree and planting it in the sea.

This passage emphasizes that faith takes hold of Christ’s victorious power. As we are united to Christ we seek to live in humble service to God and grow in comprehending that obedience to God is not about earning merit but fulfilling one’s duty in Christ’s power.
