"Verily, verily, I say unto you, Whatsoever
ye shall ask the Father in my name, he will
give it you. Hitherto have ye asked nothing
in my name: ask, and ye shall receive, that
your joy may be full.
John 16:23-24

This verse is one way we can know that our
Father in heaven wants to heal us. He wants
to answer our prayers.

Out of all the things we can ask for in prayer,
Jesus never excluded healing.
