The Holy Spirit is no skeptic. He has written neither doubt nor mere opinion into our hearts, but rather solid assurances, which are more sure and solid than all experience and even life itself.

From the beginning of my Reformation I have asked God to send me neither dreams, nor visions, nor angels, but to give me the right understanding of His Word, the Holy Scriptures; for as long as I have God's Word, I know that I am walking in His way and that I shall not fall into any error or delusion.

To preach Christ is to feed the soul, to justify it, to set it free, and to save it, if it believes the preaching.

An earthly kingdom cannot exist without inequality of persons. Some must be free, some serfs, some rulers, some subjects.

For God does not want to save us by our own but by an extraneous righteousness, one that does not originate in ourselves but comes to us from beyond ourselves, which does not arise on earth but comes from heaven.

When I am angry I can pray well and preach well.

The law works fear and wrath; grace works hope and mercy.
