23 Not doing what God tells you is far worse than fooling around in the occult. Getting self-important around God is far worse than making deals with your dead ancestors. Because you said No to God's command, he says No to your kingship.
24 Saul gave in and confessed, "I've sinned. I've trampled roughshod over God's Word and your instructions. I cared more about pleasing the people. I let them tell me what to do. 25 Oh, absolve me of my sin! Take my hand and lead me to the altar so I can worship God!" 26 But Samuel refused: "No, I can't come alongside you in this. You rejected God's command. Now God has rejected you as king over Israel." 27 As Samuel turned to leave, Saul grabbed at his priestly robe and a piece tore off. 28 Samuel said, "God has just now torn the kingdom from you, and handed it over to your neighbor, a better man than you are. 29 Israel's God-of-Glory doesn't deceive and he doesn't dither. He says what he means and means what he says." 30 Saul tried again, "I have sinned. But don't abandon me! Support me with your presence before the leaders and the people. Come alongside me as I go back to worship God."

Repentance in God is not a change of mind, as it is in us, but a change of method. The change was in Saul; "He is turned back from following me." Hereby he made God his enemy. Samuel spent a whole night in pleading for Saul. The rejection of sinners is the grief of believers: God delights not in their death, nor should we. Saul boasts to Samuel of his obedience. Thus sinners think, by justifying themselves, to escape being judged of the Lord. The noise the cattle made, like the rust of the silver, James 5:3, witnessed against him. Many boast of obedience to the command of God; but what means then their indulgence of the flesh, their love of the world, their angry and unkind spirit, and their neglect of holy duties, which witness against them? See of what evil covetousness is the root; and see what is the sinfulness of sin, and notice that in it which above any thing else makes it evil in the sight of the Lord; it is disobedience: "Thou didst not obey the voice of the Lord." Carnal, deceitful hearts, like Saul, think to excuse themselves from God's commandments by what pleases themselves. It is hard to convince the children of disobedience. But humble, sincere, and conscientious obedience to the will of God, is more pleasing and acceptable to him than all burnt-offering and sacrifices. God is more glorified and self more denied, by obedience than by sacrifice. It is much easier to bring a bullock or lamb to be burned upon the altar, than to bring every high thought into obedience to God, and to make our will subject to his will. Those are unfit and unworthy to rule over men, who are not willing that God should rule over them.

There were several signs of hypocrisy in Saul's repentance. 1. He besought Samuel only, and seemed most anxious to stand right in his opinion, and to gain his favour. 2. He excuses his fault, even when confessing it; that is never the way of a true penitent. 3. All his care was to save his credit, and preserve his interest in the people. Men are fickle and alter their minds, feeble and cannot effect their purposes; something happens they could not foresee, by which their measures are broken; but with God it is not so. The Strength of Israel will not lie.
