Faith 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 LutherThe proverb has it that Hunger is the best cook. The Law makes afflicted consciences hungry for Christ. Christ tastes good to them. Hungry hearts appreciate Christ. Thirsty souls are what Christ wants. He invites them: Come unto me, all ye that labour and are heavy laden, and I will give you rest. Christ's benefits are so precious that He will dispense them only to those who need them and really desire them.
Martin Luther
