1 Samuel 26-28

The stories in chapters 26 and 28 display the contrast between the faith of David and that of Saul. While David continued to show his faith in God, Saul resorted to a medium to seek God's plans. David was tempted to take control of Saul's death, but he refused to put himself in the place of God. Though David was a warrior he knew that all of his battles were to be against those pagans who dwelt in the Promised Land.
