1 Samuel 23-25

David's heart must have been torn. The Philistines, who he despised, were attacking the people he loved even though Saul despised David (1 Samuel 23:1). Saul had a bounty on the head of his former general, and all of David's companions faced the same threat. He didn't know what to do. So he asked God for guidance. God said "Go." But David's men lacked the faith of their leader. Why would they volunteer to save a city with the Philistine army on one side and the army of Saul on the other?  (A concern mentioned by some later followers of the Son of David (John 11:16)) David went back to the LORD and asked again. God didn't rebuke David or question him. Much like God responded to Gideon, David's prayer was answered with clarity.  Two affirmative answered convinced David's men to follow his steps of faith. They were all rewarded.
