You've heard it said that "justified" means "just as if I'd never sinned."
If that were true, we would be in trouble by the hour.
If all Christ did for us was to make us like Adam before the Fall, we are not clothed in His righteousness, we are not aware of the offense against Him we've committed, and we have no amazement at the grace He lavished upon that we would be the sons and daughters of Holy God.
Justified means MUCH MORE than "just as if I'd never sinned." It means forgiven, reconciled, and destined for glory in spite of my sin.
Praise the Lord! He does not merely make our sin go away; He paid for it on the cross and covers us in His righteousness, reconciling us to the Father by the blood of His cross.
