Written by me, JAN HENDRICKSS.
The eternal God of all grace, who has called us with a heavenly calling, from the power of Satan into his eternal, marvelous kingdom, strengthen and confirm you, my brother Maerten Janss, with his holy word, and give you the power of the Spirit, that you may be able to resist all the wicked wiles of the Evil One, whether through himself, or through his emissaries, so that you may be able to stand in this grace; and grant you and me a valiant faith, firmly rooted and grounded, that you may neither be moved nor cast down by the great tempest of false doctrine. This, I Jan Hendrickss, your weak fellow-brother in imprisonment, tribulation and affliction, wish Maerten Janss, my dear brother, in his bonds and imprisonment, as a friendly salutation in the Lord, for the refreshing of your mind. Amen.
Further, my dear brother, I inform you, that I am still of good cheer in the Lord, and my heart and mind have still no other purpose than to fear him, and to adhere to his holy word, according to my great weakness, with the help of God. Without whose assistance I am utterly powerless to perform the same. Thus I hope and am confident in my heart, that it is also with you. I furthermore thank you much for the comforting letters you have sent me to refresh and console me in my tribulation, and that you still remember me in your prayers, which I also do for you, that we may help each other fight in this great conflict, which we now have with the great red dragon, which draws the third part of the stars from heaven with his tail. Revelation 12:3,4. When I read your letters, it was no sorrow for me to hear that you were of such good cheer and courage in the Lord, but it rejoiced my spirit. Hence, my dear brother, let us take good heed to, and well consider, the teaching and admonition of Paul, where he says: “As ye have therefore received Christ Jesus the Lord, so walk ye in him, rooted and built up in him.” Col. 2:6,7. Mark, dear brother, it is needful that we attend to these words and admonition of Paul. For since we have put on Christ by baptism, and have become members of his body, let us walk in him, rooted and built up in him, and firmly abide in him, even as he says: “Abide in me, and I in you. As the branch cannot bear fruit of itself, except it abide in the vine; no more can ye, except ye abide in me. I am the vine, ye are the branches. He that abideth in me, and I in him, the same bringeth forth much fruit; for without me ye can do nothing. If a man abide not in me, he is cast forth as a branch, and is withered; and men gather them, and cast them into the fire, and they are burned.” John 15:4–6. Mark, dear brother, how well it is with him that is in Christ, and Christ in him: but he who has no consciousness of Christ, is like a branch that is cut off and withered, which receives no sap or strength, nor the nature of the stem of the vine.
Dear brother, let us now earnestly consider the matter, whether this is not the case with men. Let us therefore abound in him with thanksgiving, and by him offer the sacrifice of praise to God continually, that is, the fruit of our lips, that we be not spoiled through philosophy and vain deceit, after the traditions of men, after the rudiments of the world, and not after Christ. Heb. 13:15; Col. 2:8. “For it is now an evil time, a time that searches and tries Christians, whether they are firmly rooted and built in the faith. For when a woman has conceived, and the time of her delivery is drawing nigh, before she is delivered, great pain comes upon her, which is the forerunner and sign of her impending delivery; but when she is delivered, she soon forgets the great pain, because she has gotten a child.
