David’s hubris and his inability to practice self-control led to his greatest downfall. He committed adultery with Bathsheba and the murder of her husband Uriah. But his downfall began even before these events occurred. It began with his arrogance, his delusional belief that he was the source of his accomplishments and could therefore acquire and achieve anything he desired. He was so blinded by his delusion that Nathan’s indictment of him caught him completely off guard. Sin is like that. It convinces us that we are better than we are, and lures us away from vigilance and trust in God.
