“Samuel said to Saul, ‘I will not go back with you, for you have rejected the Lord’s orders, and the Lord has rejected you from being king over Israel!'”
1 Samuel 15.26
The Lord’s prophet refuses to support King Saul after his disobedience. He flatly informs the king of God’s rejection. The rupture is complete. Saul has a different spirit.
The Lord treats people as they treat him. When we reject his commandments, he rejects us and will no longer help us.
