Come to me, all who are weary and burdened, and I will give you rest.

Matthew 11:28

Is any one of you sick?  He should call the elders of the church to pray over him and anoint him with oil in the name of the Lord.  And the prayer offered in faith will make the sick person well; the Lord will raise him up.  If he has sinned he will be forgiven.

James 5:14-15
