When ministering a healing in jesus name how to deal with a stubborn person?

You "Baptize" them, but you do it for 15 minutes straight and you don't take their head out of the water. Even if they fight it just push them deeper and if there's some sort of stone or anything around you just smack them with it a couple times in the head. If you see red liquid its okay, just make sure they don't move, and then "heal them" in the name of Jesus.
