The book of 2 Samuel is about King David's whole heart for God. The Big Picture of 2 Samuel is:
1-10 David's Success
11 David's Sin
12-24 David's Sorrows
David is such a central theme to the Bible. He lived halfway between Abraham and Jesus. There are 66 chapters of the Bible about David, and 59 New Testament references to him. During David's reign, he not only united the Kingdom of Israel, but also led Israel to the greatest time of rule in their history. Today lower Jerusalem is considered "David's city".
David was hated by King Saul. Saul tried to kill him multiple times, and had "no heart" for God. Typically, when a new king came to the throne, the new regime "cleaned house" by killing all of the old regime. King Saul had a son named Jonathan, who was dear friends with David. Jonathan loved God. He wanted the will of God.
David and Jonathan cut covenant together (1 Samuel 18:that they would be for each other. Jonathan had a son named Mephibosheth who was dropped by his nurse while fleeing from David after Saul and Jonathan were killed in battle. As a result of the fall, Mephibosheth was crippled in both legs. Mephibosheth grew up in Lo-debar (which means a barren place), thinking that David was corrupt and that he would kill him if he knew that a descendant of Saul still lived. Of course, this was not true. On at least two occasions, while Saul was hunting David to kill him, David could have easily killed Saul - but didn't.
David finally finds Ziba, Saul's servant, who makes David aware of Mephibosheth. David welcomes in Mephibosheth with open arms. He is invited to eat at the King's table. Chapter 9:13 says, "So Mephibosheth lived in Jerusalem, for he ate always at the king's table. Now he was lame in both his feet."
***A King sought you out in a Lo-debar place, and invited you to dine at the King's table. Nome of us are "needed." We all LIMP to the cross. We limp for the rest of our lives, but it is a different limp because He adopts us into His family.***
Don't believe the lie of the enemy when it comes to SHAME - Shame says that you are never good enough...an imposter at the table. Ephesians 2:8-9 reminds us that, "for it is by grace through faith that you have been saved..."
