Since they hold to the view that the very nature of man is sin and since this nature still exists in the believer, they must hold to the view that the believer will not, in fact he can not be entirely sanctified till death. Sanctification Explained Saint, sanctify, and sanctification all have at their root in the Greek the meaning of separation. It is separation from sin and consecration to God. It is the turning from the service of sin and self to the service of God and Christ. So sanctification is essentially separation.
Sanctification is separation from sin.
This separation from sin is nothing less than the heart's full consecration to God. This is why many translators prefer the word consecration instead of sanctification. It tends to convey the idea more effectively then separation. But it is both a separation from and a consecration to. Now when I speak of the consecration of one's heart, I do not mean his emotions.
