In the third place, he says: If any preach any other gospel than I have preached, let him be accursed. Gal. 1:8. Yea, though it were an angel from heaven (mark well) yet his doctrine must not be received, if it is anything different. How should we receive for the purpose of honoring God with it, that which has proceeded from men, who are prone to wickedness from the cradle, and drink iniquity like water? Hence, what man institutes is like the labor of the spider; it can be used neither for covering, nor for clothing; but every one that hears and keeps the word of God for his salvation need add nothing to it.
Finally, I declare unto you once more in the name of my Lord: Amend your life and ways, believe the gospel, and flee idolatry. But if you yet think that you do not worship them, it is at least evident, that you serve them, kneel before them, and honor them, which God has forbidden, who requires his true statutes to be kept, and says by the prophet Jeremiah: “Obey my voice, and I will be your God, and ye shall be my people.” Jeremiah 7:23. And another prophet: “A son honoreth his father, and a servant his master: if I then be a father, where is mine honor? and if I be a master, where is my fear?” Mal. 1:6. Hence, if God is our Father, we must obey him more than men; if he is our Lord, we must honor him with that which he commands us. Then if we be reproached we will think: The servant is not better than his lord; if they have called the master of the house Beelzebub, why should they not call them of his household so? In short, he that would follow Christ to his marriage feast, must deny himself, take up the cross, and prepare his heart to suffer with Christ, in order afterwards to rejoice with him. And this suffering is short, hence it is light: do not on this account remain behind. The Lord will help me and all the godfearing through, and he will not suffer you to be tempted above that you are able to bear, but will help you to triumph, though your enemies be never so many; God is our shield, who can overcome him? Dear beloved sister, it is nothing strange that I suffer; it is a sign that the Lord loves me, and I count it for my salvation. He tries me as gold is tried in the fire; thus he tried many chosen saints of God before my time, as Abraham, Jacob, Moses, Caleb, Joshua, Daniel, John the Baptist who was the holiest of those born of women; Christ himself and his apostles, and others, were tried, as Job; but if we adhere to the Lord in temptation, the crown of eternal life is ready for us.
Herewith I will conclude this letter, kindly asking you not to reject my humble labor to you, which I have done out of great friendship. Search the Scriptures in regard to these things, and see whether they are not so. If you cannot understand or comprehend it, I kindly ask you, love your dear sister nevertheless, for she has been to me a very affectionate and faithful wife, so that I cannot thank her enough for her friendship and good company. Likewise love our only daughter, for I think that she has prolonged her beloved mother’s life, the Lord be praised. But do not lead our child to dumb idols; by so doing you would sin still more against God. Take my letter in good part; for it has been done out of a faithful heart. O Lord, grant our beloved sister thy holy knowledge, as thou didst to Saul, who also had a zeal without knowledge.
