This Epistle has been treated at length in the complete commentary (Luther’s Commentary on Galatians). It exhorts to good works or fruits of faith in those who have the Holy Spirit through faith. And it does so in a way to show that it is not the design of this doctrine to forbid good works or to tolerate and refrain from censuring bad ones, or to prevent the preaching of the Law. On the contrary it shows clearly that God earnestly wills that Christians should flee and avoid the lusts of the flesh, if they would remain in the Spirit. To have and retain the Spirit and faith, and yet to fulfil the lusts of the flesh, are two things that cannot harmonize; for “these,” Paul says, “are contrary the one to the other,” and there is between them a vehementconflict. They cannot tolerate each other; one must be supreme and cast the other out. For this reason he clearly mentions some works of the flesh which plainly and evidently are not of the Spirit, and immediately concludes that those who commit and practice these are not in a condition to inherit God’s kingdom. They have lost the Holy Spirit and faith. But he also shows whence the Christians obtain strength to enable them to resist the lusts of the flesh; namely, from the fact that they have received the Holy Spirit through faith, and from the knowledge that they have a gracious God. Thus their hearts become filled with love and a desire to obey God and to shunsin. Consequently they resist and refuse to obey the lusts of the flesh, lest they make Godangry again. And although in this conflict they still feel their weakness, the Law nevertheless cannot condemn them, because through faith they are and remain in Christ.
