I do not believe that religion can help a sick person get healed. Maybe this is the effect of auto-suggestion, in which a person heals himself. Or maybe this god helps a person to be healed. But not religion and religious figures
In most cases, faith and self-hypnosis help to heal. Religion as a doctor can only advise something, but the main process of healing is in the person himself.
This, then, is part of your religion, right?

It also affects how you think, if you think that you can be healed by the power of God from above, maybe, just maybe you will be. You can never know what is the real truth as long as you believe, it's okay.
