John Owen emphasizes that the assignation of divine honor to Christ is fundamentally rooted in faith in Him, which has been the cornerstone of true religion since the fall of man. He argues against the notion that faith in Christ was not necessary for worship and salvation, asserting that the first promise of redemption in Genesis 3:15 establishes Christ as the sole means of deliverance from sin. Owen highlights that all Old Testament sacrifices were types pointing to Christ's ultimate sacrifice, reinforcing the necessity of faith in Him for justification and salvation. He concludes that true faith in Christ encompasses both belief in His person and trust in His mediatorial work, which is essential for spiritual life and divine worship.
