(1) to set apart for God and His service
(2) to make holy
Justification - imputed righteousness
What Christ has done for us
Sanctification - imparted righteousness
What Christ is doing in us
The position we have reached is this:
(1) We have a new nature
(2) We are born again
(3) We are in union with Christ
(4) We are declared to be just
(5) We are adopted into the family
Yes, but what about the problem of sin? We have not been suddenly been made perfect. There is still the problem of sin in the life of the believer and the doctrine of sanctification deals with what God does about this.
Sin does not die within the believer, the believer dies to sin.
