What does the Bible say about shadow and substance in faith?

In Colossians 2:17, Paul explains that the religious practices of the Old Testament were merely shadows of the greater reality that is found in Christ. This theme highlights the transition from the old covenant, filled with rituals and regulations, to the new covenant established in Jesus. The shadows served to point towards deeper spiritual truths, but they cannot satisfy or save on their own. Spiritual substance, as introduced in Christ, fulfills and surpasses these earlier practices, showing that true life and worship are centered in Him and not in the externals of religion.
