Salmon was the father of Boaz (whose mother was Rahab). Boaz was the father of Obed (whose mother was Ruth). Obed was the father of Jesse. Jesse was the father of King David, who was the father of Solomon (whose mother was Bathsheba, the widow of Uriah). -Matthew 1:5-6
The Bible is full of genealogies, demonstrating how important family is to God. In these families, just like many of ours, we find people who made bad choices, who had experienced loss and found love again, whose godly parents trained them in the way that would save them even after great sin shook their family tree.
This is the family that God chose to raise up His Son; a vine of imperfect fruit, pruned and shaped, to blossom and give us the perfect sacrifice. If we dedicate our families to the service of God, just imagine what may bloom!
