Psalm 78:1, Give ear, O My people, to My teaching; incline your ears to the words of My mouth!
God’s command to Israel to hear and obey His commandments is ubiquitous in the Torah, Prophets, and Writings. Those who hate God say He is a lawmaker and a taskmaster. Yes, He made the Law, and yes, we were slaves to the Law (Romans 6:15-23). God did not give the Law to be an oppressor and a tyrant, as the God-haters claim. The Law—though it kills and does not justify—is good, holy and righteous (Romans 7:7-12; Galatians 2:16). The Law shows our imperfection—and it is for this by which it is holy and righteous—but it is also good because it shows us how to live holy lives as God’s people.
This is what the Law means for Christians today: Now that our sins have been redeemed and we have been reconciled to God by the blood of Christ on the cross, we go and do what we were created to do. How do we know what to do? The Law tells us. Thus, we give ear to God’s commands so we know how to serve and love our neighbour as God’s holy people.
