Hebrews — There are Jewish members of the church who are tempted to return to the Jewish law. The author of this epistle urges them not to look back but to move on to full spiritual maturity, by faith. Jesus Christ is better than angels and better than Moses, and He has provided a better sacrifice, a better priesthood, and a better covenant than anything in the Old Testament. Having left Egypt, we must enter the Promised Land, not continue to wander aimlessly in the wilderness.
