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.
Martin LutherAll our work in the field, in the garden, in the city, in the home, in struggle, in government-to what does it all amount before God except child's play, by means of which God is pleased to give his gifts in the field, at home, and everywhere? These are the masks of our Lord God, behind which he wants to be hidden and to do all things.
Martin LutherSo tenaciously should we cling to the world revealed by the Gospel, that were I to see all the Angels of Heaven coming down to me to tell me something different, not only would I not be tempted to doubt a single syllable, but I would shut my eyes and stop my ears, for they would not deserve to be either seen or heard.
Martin Luther
