Why the Heinous Cross (Gal 3:12,14 COD Head 2 Arts. 1, 2 RE 2)

The Lord told Adam that the day he eats of the tree of the knowledge of good and evil he will surely die. The Lord cannot just overlook his justice in order to show his mercy. Christ has to die on the cross for the Lord's justice to be satisfied. It is in Christ's death on the cross that his mercy is manifested. How does Paul use the Mosaic arrangement to give us a deeper understanding of Christ's cross?

At Peace in the Lord (1 Timothy 2:1-7)

Paul exhorts christians to live a peaceful and quiet life.  Why would Paul say such a thing?  It would seem more beneficial to be more concerned about intervening.  How are we to live this way?  How do we know that this exhortation is not the same thing as Paul saying we are merely lazy?  How do we live a meaningful life in the Lord as life in a peaceful and quiet way?

Christ Made Sin? (2 Corinthians 5:21 (LD 15; COD Head 2 Art. 2)

The Apostle Paul sure chooses some strange words when he talks about Christ’s work on the cross.  An example of strange wording regarding the work of Christ is when Paul states that Christ became sin.  What does that mean?  If we really pause for a moment that sounds like Christ has sinned so he could relate to us.  Is that what the Lord is saying through the Apostle Paul?  Why would it be problematic that Christ would sin? What does Paul mean by this language?
