When God entered into the Old Covenant with Israel at Mt. Sinai he told them that if they would obey his voice, his commandments, they would be to him “a kingdom of priests and a holy nation” (Exodus 19:6). They agreed to the terms of the covenant, saying “All that the Lord has spoken we will do” (Exodus 19:8). But the Old Covenant failed, and a new covenant was to be established to fulfill the plan of God for mankind. Why did the Old Covenant fail? What was missing? And how is what was missing in the Old Covenant accounted for in the New Covenant, so God’s purpose may be fulfilled?
And, does the replacing of the Old Covenant with the New free us, as many believe, from the obligation to obey God’s voice? His commandments?
