How do we know that the doctrine of salvation through Christ is true?

The truth of salvation through Christ is rooted in both Old and New Testament teachings. In Exodus, the sacrificial system foreshadows the ultimate sacrifice of Christ, depicted as the Lamb of God. Hebrews 12:24 connects this directly, illustrating Jesus as the mediator of a new covenant. The fulfillment of prophecy, the historical accounts of Christ’s life, death, and resurrection, and the transformative power of the Gospel in believers' lives affirm this doctrine's validity. Additionally, the theological continuity from the law to grace demonstrates God's unwavering plan for redemption, which is exclusively through His Son. Ultimately, the assurance of salvation through Christ is echoed throughout Scripture, providing a firm foundation for the Christian faith.
