21 Thus says the Lord of hosts, the God of Israel: Add your burnt offerings to your sacrifices, and eat the flesh. 22 For in the day that I brought your ancestors out of the land of Egypt, I did not speak to them or command them concerning burnt offerings and sacrifices. 23 But this command I gave them, "Obey my voice, and I will be your God, and you shall be my people; and walk only in the way that I command you, so that it may be well with you."
Matthew Henry's Commentary on Jeremiah 7:21-23
Commentary on Jeremiah 7:21-28
(Read Jeremiah 7:21-28)
God shows that obedience was required of them. That which God commanded was, Hearken diligently to the voice of the Lord thy God. The promise is very encouraging. Let God's will be your rule, and his favour shall be your happiness. God was displeased with disobedience. We understand the gospel as little as the Jews understood the law, if we think that even the sacrifice of Christ lessens our obligation to obey.
