Therefore, is thy brother a sinner? Then cover his sin and pray for him. Dost thou publish his sins, then truly thou art not a child of your merciful Father; for otherwise thou wouldst be also as he, merciful. It is certainly true that we cannot show as great mercy to our neighbor, as God has to us; but it is the true work of the devil that we do the very opposite of mercy, which is a sure sign that there is not a grain of mercy in us.
Martin LutherGod our Father has made all things depend on faith so that whoever has faith will have everything, and whoever does not have faith will have nothing
Martin LutherA large number of deaf, crippled and blind people are afflicted solely through the malice of the demon. And one must in no wise doubt that plagues, fevers and every sort of evil come from him.
Martin LutherGood works are the seals and proofs of faith; for even as a letter must have a seal to strengthen the same, even so faith must have good works.
Martin Luther
