He restores my soul. He leads me in paths of righteousness for His name's sake.
The name of God is the preaching of God, by which He is glorified and made known as the gracious, merciful, patient, truthful, and faithful one; although we are the children of wrath (Ephesians 2:3) and are guilty of eternal death, He forgives us all our sins and receives us as His children and heirs. That is His name, and that name He causes to be proclaimed through the Word. . .. Thus, without ceasing, He strengthens and restores our souls spiritually and keeps us from falling into error, and also feeds us bodily and wards off all misfortune. But only those who cling to His Word, and who believe and confess boldly that all the gifts and possessions of body and soul that they own, they have received from God purely out of grace and kindness, that is solely for His name's sake and not because of their own deeds and merits—only they give Him the honor of being exactly as we have just been told. They thank Him for His blessings and also proclaim these blessings to others.
