But know that to serve God is nothing else than to serve your neighbor and do good to him in love, be it a child, wife, servant, enemy, friend....If you do not find yourself among the needy and the poor, where the Gospel shows us Christ, then you may know that your faith is not right, and that you have not yet tasted of Christ's benevolence and work for you.
Martin LutherAlways preach in such a way that if the people listening do not come to hate their sin, they will instead hate you
Martin LutherEverything that is done in the world is done by hope. No merchant or tradesman would set himself to work if he did not hope to reap benefit thereby.
Martin LutherLook to it that you do not try to do all of it, do not try to do too much, lest your spirit grow weary. Besides, a good prayer mustn't be too long. Do not draw it out. Prayer ought to be frequent and fervent.
Martin Luther
