"The covenant law comes after the exodus. That is, we have eighteen chapters of salvation in Exodus before we have a single chapter of law. Only after the story of salvation do we come to Sinai (Ex 19), the ten commandments (Ex 20) and the making of the covenant (Ex 24). The Sinai covenant, like all covenants, is founded on God's grace and motivated by God's mission. That is to say, it looks back to what God had already done for Israel out of his love and grace in delivering them from slavery, and it looks forward to God's purpose within history through Israel - to make them the instrument of his blessing to the nations."

In the same frequency, the gospel says, "I'm accepted; therefore, I obey."
