[Christ's] mission and work it is to help against sin and death, to justify and bring life. He has placed his help in baptism and the Sacrament [i.e., communion/Eucharist/Lord's supper], and incorporated it in the Word and preaching. To our eyes Baptism [capitalized in original] appears to be nothing more than ordinary water, and the Sacrament of Christ's body and blood simple bread and wine, like other bread and wine, and the sermon, hot air from a man's mouth. But we must not trust what our eyes see.

Martin LutherWhen asked what he would do if he knew the world would end tomorrow, Martin Luther said, "I would plant a tree."
Martin LutherThe kingdom of God does not consist in talk, but in power, that is, in works and practice. God loves the 'doers of the word' in faith and love, and not the 'mere hearers,' who, like parrots, have learned to utter certain expressions with readiness.
