1 Samuel 15:13

I have performed. With an apparent show of great respect, Saul waited expectantly to receive Samuel’s commendation. Like men all through the course of history, Saul was ready to believe that he had carried out the commission given him, merely by performing that part of it that was agreeable to him. He had made a foray against the traditional enemies of Israel, and had returned with Agag as proof of the accomplishment of his mission. The victory monument erected in Carmel is evidence of his self-satisfaction. Like Saul of Tarsus, Saul the son of Kish had no doubt come to believe that acts of his own choosing were performed in harmony with God’s will. But here, of course, similarity between the two ends, for the one knew the will of God and did it not, but the other acted in ignorance (1 Tim. 1:13).
