Hosea 14:4

Freely— Are good works then nothing, you will say? "Is there no place at all for them in the doctrine of repentance? I answer, that hitherto the discourse hath been about remission of sins, and the gift of the Holy Ghost. These are entirely gratuitous, and not of our merit, but simply of the inexhaustible goodness and compassion of God. Therefore, when we speak of the remission of sins, it is right to be silent about our own works; which, because they are done without the Holy Spirit, although with regard to civil society they may not be bad, yet cannot be called good, and ought not; because of the unclean heart, from which they proceed. But when through faith we have received remission of sins, and, together with that, the gift of the Holy Ghost; forthwith from the heart, as from a pure fountain, come forth works also good, and well-pleasing to God," &c. See Luther's Commentary upon this chapter.
