How do we know Christ is the Lamb of God?

We have confidence that Christ is the Lamb of God through both Old Testament prophecies and New Testament affirmations. In Genesis 22, Abraham proclaimed that God would provide Himself a lamb, foreshadowing the coming of Christ as the ultimate sacrifices (Genesis 22:8). John the Baptist, recognizing Jesus, clearly identifies Him as the Lamb of God in John 1:29. Additionally, in Revelation, Christ is frequently described as the Lamb, indicating His ongoing role in the eternal redemptive plan. This consistent biblical narrative from Genesis to Revelation affirms that Jesus embodies the sacrificial system established in the Law, ultimately fulfilling it by offering Himself for our sins (Hebrews 10:12).
