We conclude therefore with Paul, that we are justified by faith only in Christ, without the works of the law. Now after that a man is once justified, and possesseth Christ by faith, and knoweth that He is his righteousness and life, doubtless he will not be idle, but as a good tree he will bring forth good fruit. For the believing man hath the Holy Ghost, and where the Holy Ghost dwelleth He will not suffer a man to be idle, but stirreth him up to all exercises of piety and godliness, of true religion, to the love of God, to the
patient suffering of afflictions, to prayer, to thanksgiving, to the exercise of charity towards all men.
Martin Luther, Kregel, Galatians 2:18, p. 82.
