Mephibosheth was King Saul's grandson. He was crippled in both feet living in Lo Debar (no pasture). As was common practice at the time, he was fully expecting to be exiled or put to death by King David's  bodyguards. Instead David does the opposite. He invites him to his table to show kindness to him and his family  on behalf of Jonathan, and thus restores his fortunes and his dignity. We too are like Mephibosheth. We may feel inwardly crippled, stuck in a place of barrenness, but King Jesus is inviting us to the table of grace to restore us and bless us with his "Hesed" - OT grace or loving kindness. With the kindness and love we receive in the grace of our Lord Jesus Christ we are able to reach out and minister to people who are broken and lost like Mephibosheth while he was in Lo Debar
