Luther Addresses the Problems that Occur When Christians Misunderstand Predestination, pt. 4

Staupitz used to comfort me with these words: “Why do you torture yourself with these speculations? Look at the wounds of Christ and at the blood that was shed for you. From these predestination will shine. Consequently, one must listen to the Son of God, who was sent into the flesh and appeared to destroy the work of the devil (1 John 3:8) and to make you sure about predestination. And for this reason He says to you: ‘You are My sheep because you hear My voice’ (cf. John 10:27). ‘No one shall snatch you out of My hands’ ” (cf. v. 28).

Many who did not resist this trial in such a manner were hurled headlong into destruction. Consequently, the hearts of the godly should be kept carefully fortified. Thus a certain hermit in The Lives of the Fathers advises his hearers against speculations of this kind. He says: “If you see that someone has put his foot in heaven, pull him back. For this is how saintly neophytes are wont to think about God apart from Christ. They are the ones who try to ascend into heaven and to place both feet there. But suddenly they are plunged into hell.” Therefore the godly should beware and be intent only on learning to cling to the Child and Son Jesus, who is your God and was made flesh for your sake. Acknowledge and hear Him; take pleasure in Him, and give thanks. If you have Him, then you also have the hidden God together with Him who has been revealed. And that is the only way, the truth, and the life (cf. John 14:6). Apart from it you will find nothing but destruction and death.

But He manifested himself in the flesh to snatch us from death, from the power of the devil. From this knowledge must come great joy and delight that God is unchangeable, that He works in accordance with unchangeable necessity, and that He cannot deny Himself (2 Tim. 2:13) but keeps His promises. Accordingly, one is not free to have such thoughts or doubts about predestination; but they are ungodly, vicious, and devilish. Therefore when the devil assails you with them, you should only say: “I believe in our Lord Jesus Christ, about whom I have no doubt that He was made flesh, suffered, and died for me. Into His death I have been baptized.” This answer will make the trial disappear, and Satan will turn his back.
