Christ is no Moses, no exactor, no giver of laws, but a giver of grace, a Savior; he is infinite mercy and goodness, freely and bountifully given to us.
Martin LutherThe 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.
Martin LutherOnce sure that the doctrine we teach is God's Word, once certain of this, we may build thereupon, and know that this cause shall and must remain; the devil shall not be able to overthrow it, much less the world be able to uproot it, how fiercely soever it rage.
Martin Luther
