“For I spake not unto your fathers, nor commanded them in the day that I brought them out of the land of Egypt, concerning burnt offerings or sacrifices:”
King James Version (KJV)
Matthew Henry's Concise Commentary
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.
“O LORD of hosts, God of Israel, that dwellest between the cherubims, thou art the God, even thou alone, of all the kingdoms of the earth: thou hast made heaven and earth.”
