As we move from the Old Testament to the New Testament, we look at the genealogy of Jesus, going all the way back to Abraham. What we find is that there are many names that stand that Matthew mentions, as we remember stories of the Old Testament. Names like "Father" Abraham, Jacob, Judah, Tamar, Rahab, and "the wife of Uriah." All this is to say: God worked through sinful people AND their sinful actions to bring about his plan of salvation.
