19 Why haven't you obeyed the Lord ? Why did you rush for the plunder and do what was evil in the Lord 's sight?" 20 "But I did obey the Lord," Saul insisted. "I carried out the mission he gave me. I brought back King Agag, but I destroyed everyone else. 21 Then my troops brought in the best of the sheep, goats, cattle, and plunder to sacrifice to the Lord your God in Gilgal." 22 But Samuel replied, "What is more pleasing to the Lord : your burnt offerings and sacrifices or your obedience to his voice? Listen! Obedience is better than sacrifice, and submission is better than offering the fat of rams. 23 Rebellion is as sinful as witchcraft, and stubbornness as bad as worshiping idols. So because you have rejected the command of the Lord, he has rejected you as king."
24 Then Saul admitted to Samuel, "Yes, I have sinned. I have disobeyed your instructions and the Lord 's command, for I was afraid of the people and did what they demanded.

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.
Commentary on 1 Samuel 15:24-31
(Read 1 Samuel 15:24-31)
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.
