How do we know Jesus is the promised Lamb?

The promise of the Lamb is evident from the very beginning of Scripture. In Genesis 22, God instructed Abraham to sacrifice his son Isaac but provided a ram instead, showcasing His provision of a substitute (Genesis 22:8). This foreshadows the ultimate sacrifice of Jesus. Additionally, John the Baptist explicitly identifies Jesus as the Lamb of God who takes away the sins of the world (John 1:29), affirming that He fulfills the prophetic word and the need for a perfect sacrifice. Thus, Jesus stands as the culmination of God’s promise to provide Himself as the Lamb, a reality of grace that echoes through the ages.
