1 Samuel 18:10-11

The next day an evil spirit from God rushed upon Saul and he prophesied within his house. Now David was playing the lyre that day. There was a spear in Saul’s hand,  and Saul threw the spear, thinking, “I’ll nail David to the wall!” But David escaped from him on two different occasions.

Today we have a truth that at a glance, can threaten who you believe God to be. God sent an evil spirit on Saul, the King of Israel. Saul was named King because Israel demanded a King from God...and it didn't take Saul long to show God that He was not the man for the job. This evil spirit sets the stage for God's man (David), to be raised up in the eyes of Israel through conflict with Saul. Our God is the King of Kings, and He proves it here, as Saul's reign starts falling apart at the hand of God...because of his disobedience.
