Christmas Generations (Matthew 1:1-17)

When we summarize  our history we tend to avoid the embarrassing people in our family line.  We all have those relatives that we do not like to talk about because of what they have done or what they are currently doing.  So, when our Lord lays out the genealogy of Chris you would think that He is going to call to our attention the good people and ignore the embarrassing ones?  Well, if you look at the genealogy some of the most embarrassing skeletons in the closet are brought out front and center.  Why would our Lord do that?  Why would our Lord even give us a genealogy at all?
