The words of God are foolish to men and of no weight. For if they esteemed them as precious, wise, and good, they would undoubtedly not have thus disdained them. They can indeed say that they love and esteem the Word of God, but they deny it by their deeds. They can also say that they hate the world and regard it as nothing, but they approve of it by their deeds. For when they reach out all day and night for those things that are of the world, yes, week after week, but do not reach out for the Word of God on a festival day, it is plainly evident that “they do not rejoice but sicken at Your words,” like the Jews in the wilderness, who found many things lacking and no spoils. And this is a clear demonstration that the world is the image of hell and a model and forerunner of the damned, yes, like the lodging of the devil and ungodliness, which consistently ignores the Word of God and its immeasurable benefits and does not see them and most basely despises them. (Luther’s Works, v. 11, p.519)

Therefore he says in opposition to both: “I am neither afraid of you, nor will I rejoice with you, for there are other things that I fear and other things in which I will rejoice; I fear Him who can destroy into hell, and not the princes who kill the body (Matt. 10:28). And I will rejoice at the words of God, and not at the presence of your pleasure.” He compares himself to one finding many spoils. And how does he rejoice, I ask? I think that he rejoices in the manner which the Lord describes in Matt. 13:44, that a man who found a treasure hidden in a field hid it and went for joy, etc. He rejoices, but not openly. He alone knows his joy, because he alone knows his good. If he had published it, then the field would certainly not have been sold to him, and he would not have gained possession of the treasure. Or if he had possessed it, he would have possessed it with danger. Such is the joy of the Spirit, because it is in secret, because he alone knows, because also he alone knows his spiritual good.
