Saul and David are perfect examples of a rebellious heart and a submitted heart. Neither men were perfect. But what sets them apart is the posture of their heart. Saul’s heart was consistently rebellious, while David’s was consistently submitted.
Saul
When Saul was confronted with his sin, he explained and excused himself, revealing his disobedience and his mistrust in the Lord. He followed his whims rather than seeking the Lord’s guidance. Saul’s life tells us that rebellion is the result of pride.
Rebellion will move you from a place of blessing and safety to a place of danger and disaster.
David
However, when confronted with his sin (2 Samuel 12), David’s response was tender and responsive. He listened to the message from the Lord, confessed his sin, had a humble heart, and sought after righteousness.
