I am thankful that we do not have to be like Elijah and call down fire from heaven. In fact our Father does not have to defended Himself at all. My point is this be careful as to how we challenge none believers. God does do signs and wanders we do not do them for Him. He does them so that He can receive glory for Himself and Him alone. Always pray for the sick, always pray for people for there needs are met .If you can meet the need then do it.
