From time to time I come across people who think they are Lutherans but in fact have embraced the modern antinomianism. In their eyes, it is wrong to encourage Christians to do good works; particularly egregious is the mention of rewards for good works. All that is "legalism" and "works-righteousness." The fact that the New Testament is replete with references to these matters is irrelevant. Here is a passage that, were it not from the Apology, would be rejected by the aforementioned:
Here also we add something about rewards and merits. We teach that rewards have been offered and promised for the works of believers. We teach that good works have merit, not for forgiveness of sins, for grace, or for justification (for these we receive only through faith), but for other rewards, bodily and spiritual, in this life and after this life. For Paul says in 1 Corinthians 3:8, "Each will receive his wages according to his labor." There will be different rewards according to different labors. But forgiveness of sins is given alike and equal to all people, just as Christ is one, and is offered freely to all who believe that for his sake their sins are forgiven.
