Exodus 15:26 "And said, If you will diligently hear to the voice of the Lord your God, and will do that which is right in his sight, and will give ear to his commandments, and keep all his statutes, I will put none of these diseases upon you, which I have brought upon the Egyptians for I am the Lord that heal you."
Mark 16: 15-18 "And He said to them, “Go into all the world and preach the gospel to every creature. He who believes and is baptized will be saved; but he who does not believe will be condemned. And these signs will follow those who believe: In My name they will cast out demons; they will speak with new tongues; they will take up serpents; and if they drink anything deadly, it will by no means hurt them; they will lay hands on the sick, and they will recover.”
James 5:13 - 16 "Is anyone among you suffering? Let him pray. Is anyone cheerful? Let him sing psalms. Is anyone among you sick? Let him call for the elders of the church, and let them pray over him, anointing him with oil in the name of the Lord. And the prayer of faith will save the sick, and the Lord will raise him up. And if he has committed sins, he will be forgiven. Confess your trespasses to one another, and pray for one another, that you may be healed. The effective, fervent prayer of a righteous man avails much.
