These quotes comparing justification and sanctification are from one of my favorite books, True Spirituality, by Francis Schaeffer.
“In justification, the basis is the finished work of Jesus Christ; in sanctification, it [also] is the finished work of Christ. In justification, we must see, acknowledge, and act upon the fact that we cannot save ourselves. In sanctification we must see, acknowledge, and act upon the fact that we cannot live the Christian life in our own strength or our own goodness… In justification, the instrument by which we receive the free gift of God is faith… In sanctification the instrument by which we receive the free gift of God is faith… As justification deals with our guilt, and sanctification deals with the problem of the power of sin in our lives as Christians, justification is once for all, while [sanctification] is moment by moment… Our calling is to believe God, raise the empty hands of faith, and let [the Spirit’s] fruit flow out through us.”
