Rom 8:31 says "If God is for us, who can be against us?" I don't know how you feel about this truth and I have no great experience on it - at least not that I can compare with David in 1 Sam 19 =) Saul set out to kill David but who is on Saul's side? His son, Jonathan, helped David and the evil spirit tried to kill David through Saul's hand was not successful either. Saul's daughter, Michal also helped David to escape from his hand and the spirit of God also came into play. What an amazing preservation of David's life through God's Almighty hand!
