But now let us proceed to the remaining matters and first of all consider the wonderful example of God’s government in Jacob, namely, how God brings His saints down to hell and leads them back again, comforts and saddens them, that we may become accustomed to trust His Word alone and cling to it. For the affairs of the godly must be brought to the point that they feel nothing, understand nothing else, and see nothing on which to rely, especially in death, but the Word. Accordingly, let us learn to die according to the flesh and to depend on the Word so that even if the world were to be shattered and totter,21 we may nevertheless confidently say: “I believe in God the Father, etc., and in Jesus Christ, His Son, etc.” But Jacob now lives in Hebron and has a son of 17 who is the hope and comfort of his old age. He thinks that his troubles are over, and now he finds himself in a worse plight than he had experienced in his whole life.
