God foreknows nothing by contingency, but that He foresees, purposes, and does all things according to His immutable, eternal, and infallible will. By this thunderbolt, "Free-will" is thrown prostrate, and utterly dashed to pieces.
Martin LutherThe dog is the most faithful of animals and would be much esteemed were it not so common. Our Lord God has made His greatest gifts the commonest.
Martin LutherTake a look at your own heart, and you will soon find out what has stuck to it and where your treasure is. It is easy to determine whether hearing the Word of God, living according to it, and achieving such a life gives you as much enjoyment and calls forth as much diligence from you as does accumulating and saving money and property.
Martin Luther
