King Saul started out knowing God's will and following it. Later in life he turned to and continuously sought his own good, even when it was in contradiction to the will of God. He did not completely destroy the Amalekites as he was told to, instead he allowed some of the people to take plunder for their own benefit, though he said it was for sacrifice. Then he sought to kill David - who was to be his successor - though David proved over and over again that he was faithful to Saul's leadership and would be till he died. He continued to ignore God's law. He slaughtered a whole city of priests in his pursuit of David, and even threw a spear at his oldest son, Jonathan, because of his friendship with David. Finally God ceased to speak to him at all. In I Samuel 28, the Philistines gathered their forces to come against Israel. After seeing the army of the Philistines, Saul decided to seek God, presumably because he was afraid they were too much for him. But God did not send any message, not by a dream, or by prophets. Even the Urim, a device used by the priests, was silent. Then Saul went to a medium, a person who talks with dead people. This practice is expressly forbidden in the law of God. That worked, sort of. However, Saul never showed any real repentance for any of his sins and he died in that battle, along with all of his sons.
