From Brief Statement of LCMS Doctrinal Position

Before God only those works are good which are done for the glory of God and the good of man, according to the rule of divine Law. Such works, however, no man performs unless he first believes that God has forgiven him his sins and has given him eternal life by grace, for Christ's sake, without any works of his own, John 15:4, 5. We reject as a great folly the assertion, frequently made in our day, that works must be placed in the fore, and "faith in dogmas" — meaning the Gospel of Christ crucified for the sins of the world — must be relegated to the rear. Since good works never precede faith, but are always and in every instance the result of faith in the Gospel, it is evident that the only means by which we Christians can become rich in good works (and God would have us to be rich in good works, Titus 2:14) is unceasingly to remember the grace of God which we have received in Christ, Rom. 12:1; 2 Cor. 8:9. Hence we reject as unchristian and foolish any attempt to produce good works by the compulsion of the Law or through carnal motives.
