Luther on the Necessity of Preaching Sanctification

“For a Christ who died for sinners who, after receiving forgiveness, will not quit their sin nor lead a new life, is worthless and does not exist…. There is nothing in their preaching concerning sanctification of the Holy Ghost and about being quickened into a new life. They preach only about the redemption of Christ. It is proper to extol Christ in our preaching; but Christ is the Christ and has acquired redemption from sin and death for this very purpose that the Holy Spirit should change our Old Adam into a new man, that we are to be dead unto sin and live unto righteousness, as Paul teaches Rom 6.2 ff., and that we are to begin this change and increase in this new life here and consummate it hereafter. For Christ has gained for us not only grace (gratiam), but also the gift (donum), of the Holy Ghost, so that we obtain from Him not only forgiveness of sin, but also the ceasing from sin. Any one, therefore, who does not cease from his sin, but continues in his former evil way must have obtained a different Christ, from the Antinomians. The genuine Christ is not with them, even if they cry with the voice of all the angels, Christ! Christ! They will have to go to perdition with their new Christ.” Martin Luther Concerning Councils and Churches, as quoted by C.F.W. Walther in The Proper Distinction Between Law and Gospel, 121-122
