21 Thus says the Lord of hosts, the God of Israel: "Add your burnt offerings to your sacrifices and eat meat. 22 For I did not speak to your fathers, or command them in the day that I brought them out of the land of Egypt, concerning burnt offerings or sacrifices. 23 But this is what I commanded them, saying, 'Obey My voice, and I will be your God, and you shall be My people. And walk in all the ways that I have commanded you, that it may be well with you.' 24 Yet they did not obey or incline their ear, but followed the counsels and the dictates of their evil hearts, and went backward and not forward. 25 Since the day that your fathers came out of the land of Egypt until this day, I have even sent to you all My servants the prophets, daily rising up early and sending them. 26 Yet they did not obey Me or incline their ear, but stiffened their neck. They did worse than their fathers. 27 "Therefore you shall speak all these words to them, but they will not obey you. You shall also call to them, but they will not answer you. 28 "So you shall say to them, 'This is a nation that does not obey the voice of the Lord their God nor receive correction. Truth has perished and has been cut off from their mouth.

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.
