The Blessing of Imputation

19, To wit, that God was in Christ, reconciling the world to himself, not imputing their trespasses to them; and has committed to us the word of reconciliation.
20, Now then we are ambassadors for Christ, as though God did beseech you by us: we pray you in Christ's stead, be you reconciled to God.
21, For he has made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him.
