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. All we like sheep have gone astray; we have turned every one to his own way; and the Lord hath laid on him the iniquity of us all. - Isaiah 53:5-6 (King James Version)
Even from the Old Testament prophet Isaiah we have the doctrine of once saved always saved; that we are healed with His stripes, we are not in need of some other work, all is in Christ Jesus, not in our works.
God bless!
