From the Bible...

Is any sick among you? 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 shall save the sick, and the Lord shall raise him up; and if he have committed sins, they shall be forgiven him.
Confess your faults one to another, and pray one for another, that ye may be healed. The effectual fervent prayer of a righteous man availeth much.
James 5:14-16

Surely he hath borne our griefs, and carried our sorrows: yet we did esteem him stricken, smitten of God, and afflicted.
But he was wounded for our transgressions, he was bruised for our iniquities: the chastisement of our peace was upon him; and with his stripes we are healed.
Isaiah 53:4-5

Who his own self bare our sins in his own body on the tree, that we, being dead to sins, should live unto righteousness: by whose stripes ye were healed.
1 Peter 2:24

Jesus answered and said unto them, Go and show John again those things which ye do hear and see:
The blind receive their sight, and the lame walk, the lepers are cleansed, and the deaf hear, the dead are raised up, and the poor have the gospel preached to them.
Matthew 11:4-5

And Peter, fastening his eyes upon him with John, said, Look on us.
And he gave heed unto them, expecting to receive something of them.
Then Peter said, Silver and gold have I none; but such as I have give I thee: In the name of Jesus Christ of Nazareth rise up and walk.
And he took him by the right hand, and lifted him up: and immediately his feet and ankle bones received strength.
And he leaping up stood, and walked, and entered with them into the temple, walking, and leaping, and praising God.
Acts 3:4-8
