As followers of Jesus Christ we have become descendants of Abraham through faith. The author of Hebrews urges us to imitate Abraham’s faith and inherit the marvelous promises (and oath) he gave to the patriarch thousands of years ago.
Unbelief was a deadly disease that kept Israel from believing God’s “good news” and ultimately kept them from the Promised Land. We too, like Israel, if we allow unbelief to go unchecked, can end up in all-out rejection of God (apostasy) if we are not diligent to preserve our faith.
If the old covenant had sanctions because of negligence or disobedience, how much greater will the new covenant sanctions be given Christ’s superiority! For this reason (and many others), as new covenant believers, we must pay more careful attention to the message we have been privileged to receive.
