Indirectly, we have already been discussing the relationship between justification and sanctification. Now, we will be more specific as to their interrelationship. What is meant by these two terms? Justification is an act of God's grace in which the sinner is declared righteous, not by any good works that he has done but by the work of Christ which is credited to his account. It is a one-time judicial act of God. Romans 8:1 captures the effect of justification. There is now no condemnation to those who are in Christ Jesus.
