3 And the king said, Is there not yet any of the house of Saul, that I may shew the kindness of God unto him? And Ziba said unto the king, Jonathan hath yet a son, which is lame on his feet.
6 Now when Mephibosheth, the son of Jonathan, the son of Saul, was come unto David, he fell on his face, and did reverence. And David said, Mephibosheth. And he answered, Behold thy servant!
7 And David said unto him, Fear not: for I will surely shew thee kindness for Jonathan thy father’s sake, and will restore thee all the land of Saul thy father; and thou shalt eat bread at my table continually.
-Mephibosheth is the grandson of Saul and so is the product of a bloodline that is reproached before the Lord. If that wasn’t bad enough, he is lame on both feet. He is, by all account, worthless. Yet, David seeks him out for the explicit purpose of giving him a place at the King’s table, as one of the King’s sons. David doesn’t do it because he found some worth in Mephibosheth; rather he does it for the sake of his friend Jonathan. The Bible contains another story about a group of people who come from a cursed bloodline and are completely worthless. In that story another Great King seeks out those worthless people in order to give them a place at His table and to make them as His own sons and daughters. That Great King is the Lord, those worthless people are you and me and just as David gave so much for the sake of Jonathan, The Lord sees fit to give us Salvation and Righteousness for the sake of Jesus Christ.
