The Devil, it is true, is not exactly a doctor who has taken degrees, but he is very learned, very expert for all that. He has not been carrying on his business during thousands of years for nothing.
Martin LutherFaith is a living, daring confidence in God's grace, so sure and certain that a man would stake his life on it one thousand times. This confidence in God's grace and knowledge of it makes men glad and bold and happy in dealing with God and with all creatures; and this is the work of the Holy Ghost in faith.
Martin Luther
