Why is it that some people when they pray for your healing ask you afterwards to do something that you couldn’t do before? For example move your leg, your arm, etc? Is this scriptural?
No, this is not Scriptural. These people are looking for evidence that the prayer “worked”. It usually shows a lack of faith on their part, because if you can’t demonstrate that a healing has taken place, they will walk away thinking that maybe it hasn’t. Paul said we are to walk by faith not by sight (2 Cor. 5:7). Even if nothing happens immediately following a healing prayer, we are to accept by faith that God has heard us and will respond.
