Anyone can pray for healing as long as He is a firm believer of Jesus!
"Is anyone of you sick? Then you should call the leaders of your church to pray over you and anoint you with oil in the name of the Lord. Then the prayer that is offered in faith will make the sick person well and the Lord will restore that person to health. And if that person has sinned, he will be forgiven. So then, confess your sins to each other and pray for each other so that you may be healed!" James 5:13-14
