If I could I would heal myself HaHa
I dont think so either................I think most would say they base this on this verse..................[Mat 17:20 KJV] 20 And Jesus said unto them, Because of your unbelief: for verily I say unto you, If ye have faith as a grain of mustard seed, ye shall say unto this mountain, Remove hence to yonder place; and it shall remove; and nothing shall be impossible unto you.
Take a look at what scripture says about faith and healing
[Mat 10:1 KJV] 1 And when he had called unto [him] his twelve disciples, he gave them power [against] unclean spirits, to cast them out, and to heal all manner of sickness and all manner of disease.
Jesus gave them power to heal
[Mar 4:40 KJV] 40 And he said unto them, Why are ye so fearful? how is it that ye have no faiith?
[Mat 16:8 KJV] 8 [Which] when Jesus perceived, he said unto them, O ye of little faith, why reason ye among yourselves, because ye have brought no bread?
Was the power to heal based on having enough faith? The disciples power to heal was not based on faith
