Healing
These two verses are all you need to realise that Jesus Christs blood hath healed you and for those that argue against using Isaiah for the sake that it was before Christs death well that just supports the truth that you are healed. For if you could be healed before it happened doesn't it seem logical that the healing power of the blood would be stronger after it happened not weaker.
Isaiah 53:5 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.
1 Peter 2:24 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.
