The Bible makes it clear that Jesus does not heal impersonally or arbitrarily, but relationally and personally.
Have you ever wondered why there are no records of Jesus randomly emptying out hospitals or asylums with the wave of his healing hand? The reason is because God does not heal arbitrarily or impersonally. God’s healing is the result of being in relationship with him. The great physician heals us, the closer we get to him the more whole, thus healed we become. That is why death for the follower of Jesus is a great victory. It is the ultimate healing for the believer- because it presents the opportunity to be the closest to God.
