It is not speaking of our habits. It is speaking of our relationship to God. We were sinners, now we are sons. We were condemned, now we are justified. We were enemies, now we have fellowship with God.
Reconciliation goes beyond forgiveness.
You can forgive someone without being reconciled to that person. You may put away the offense, but not restore the relationship. God has done both. He has not only put away our past debt of sin, but He has also Brought us into His family, Prepared a place for us in His heaven, and Promised that we will be with Him for all eternity. We've been made the righteousness of God God took my sins, and charged them to Christ's account.
