From Luther’s sermon for the seventh Sunday after Trinity (1534):
Thus St. Paul says: “Know ye not, that to whom ye yield yourselves servants to obey, his servants ye are to whom ye obey: whether of sin unto death, or of obedience unto righteousness?” and this means, as you now through grace are bound to obey God and live according to His Will. For you must be in the service of one master, either of sin which brings you into death and the wrath of God, if you remain in it it, or of God in grace, to serve Him in newness of life. Therefore you must no longer be obedient to sin, for you are now released from its power and dominion.
Sin will not be able to rule over you, for you are no longer under the Law but under grace. That is, you can now resist sin because ye are now in Christ and have received the power of His resurrection.
Either Luther was reading Vos, or the forensic-centric reputation of Lutherans is a caricature. Or maybe the priority of justification was biblical after all.
