For in the true nature of things, if we rightly consider, every green tree is far more glorious than if it were made of gold and silver.
Martin LutherTherefore, 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 LutherThe human heart is like a millstone in a mill: when you put wheat under it, it turns and grinds and bruises the wheat to flour; if you put no wheat, it still grinds on, but then 'tis itself it grinds and wears away.
Martin Luther
