1 Corinthians 2:12:

Now we have received, not the spirit of the world, but the spirit which is of God; that we might know the things that are freely given to us of God.

Notes on 1 Corinthians 2:12:

God wants every person to know that healing has been freely given to him.  The Holy Spirit will help illuminate you on this matter.  When you realize that healing has been freely given to you by God, you’ll know better than to ever beg Him for it again!
