While standing on Mt. Zion, Baruch hears a voice from heaven. The Lord answers an objection Baruch raised in his lament (chapter 13). This is a dialogue between God and Baruch which deals with the problem of the destruction of temple (13-20). What good is it to follow God if he allows the Temple to be destroyed and the people judged so harshly? People may ask, “why has God brought this sort of destruction down on his people?” When these people wonder if such a retribution will come upon them, Baruch is to tell them that they will also drink the wine of God’s wrath down to the dregs. After hearing this, Baruch asks the Lord what benefit is there in being righteous if everyone will be punished by the Lord (chapter 14).
In chapter 19), The Lord points out Moses who gave them the covenant and they were judged by that standard. How happy a person is while young does not really matter if at the end of his life he transgresses and is judged. The Lord’s point seems to be that there is still time for repentance near the “end of days” for the nation. Baruch is told to go and fast for seven days and the Lord will continue his revelation to Baruch (chapter 20).
Chapter 21 contains a prayer of Baruch in response to the dialogue of chapters 13-20. In verse 4-11 he calls out to the Lord as the creator God, the God who is sovereign and in control of his creation. He decrees things so minutely he knows how many raindrops will fall on a given head (cf. Mt. 10:30, the hairs on one’s head are numbered.) Verses 12-18 develop this theme of God’s knowledge acknowledge that God has preserved the life of those who have sinned so that they may be proved righteous. Men are changeable even if God is not and God takes the time to change men. In verses 19-25 Baruch asks how long it will be that the world will continue to be polluted by sin.
Finally, He asks for God to act to reveal his glory in the world and restore creation. The restoration in mind is Israel, but this restoration will mean salvation for all creation. This resonates with Revelation, at least in the sense that the final restoration is the return of the glory of God and a “new heavens and new earth.”
