God Regulates Worship through Scripture

God Himself regulates the worship of Himself. We as fallen beings cannot invent better ways of worshipping God than the very ways he has established for us. Even the first covenant had regulations. If we cannot even know our hearts how could we think we could add to or take away what God has given us.

All men are in covenant with God. Whether in fallen Adam (the Covenant of Works) or in Christ (the Covenant of Grace). No one has ever been or will be saved except in Christ. Luke 24:26-27
