Luther on Sin after Baptism

“Indeed, Christ once and for all absolved and freed everyone from sin and death when He merited for us the law of the Spirit of the Life. But what did that Spirit of Life do? He has not yet freed us from death and sin, for we still must die, we still must labor under sin; but in the end He will free us. Yet He has already liberated us from the law of sin and death, that is, from the kingdom and tyranny of sin and death. Sin is indeed present, but having lost its tyrannic power, it can do nothing; death indeed impends, but having lost its sting, it can neither harm nor terrify. These then are two places in which Paul calls “sin” that evil which remains after baptism” (“Against Latomus,” LW 32, 207).
