John 8:36 So if the Son sets you free, you will be free indeed
But He was pierced for our transgressions, He was crushed for our iniquities; the punishment that brought us peace was upon Him, and by His stripes we are healed. HE SENT HIS WORD AND HEALED THEM, AND DELIVERED THEM FROM THEIR DESTRUCTIONS.
