Martin LutherPrayer is a very precious medicine, one that certainly helps and never fails, if you will only use it.
Martin LutherBut 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 Luther
