The Lamb of God

Season 2 Episode 3

Stained glass depiction of Christ’s crucifixion—Reformed theological reflection on Jesus as the Lamb of God who takes away the sin of the world.

Special Guest: Cory Reckner

Behold the Lamb of God

John the Baptist’s words in John 1:29 are simple but loaded with meaning: “Behold, the Lamb of God, who takes away the sin of the world.” In this episode of The Restless Theologian, part of our Christology series, I talk with Cory Reckner about what that title means, why it runs through the whole Bible, and how it shows us God’s plan to save His people.

Old Testament Roots of the Lamb

The picture of the lamb as a substitute starts early. Think about Abraham and Isaac on Mount Moriah—God provides a lamb in place of Abraham’s son. In Egypt, the Passover lamb’s blood protected Israel from judgment. Then there’s the whole Levitical system, where lambs were offered as part of Israel’s worship. All of it pointed ahead. All of it was preparing God’s people for the One true Lamb who would take away sin completely.

Jesus as the Fulfillment

When John the Baptist calls Jesus the Lamb of God, he isn’t just being poetic. He’s saying, “This is the One. This is the sacrifice every other sacrifice was pointing toward.” Jesus is the spotless Lamb, the once-for-all offering who bears the sin of the world. His crucifixion wasn’t an accident. It was the center of God’s eternal plan—a plan set in motion before the foundation of the world.

The Lamb Who Reigns

The story doesn’t stop at the cross. In Revelation, the Lamb is on the throne. He’s still called the Lamb who was slain, but now He’s exalted and worshiped by the hosts of heaven. That’s the paradox—meekness in His suffering, majesty in His victory. And it’s a victory that’s final. As we explored in The Son of God, His reign is rooted in His identity, and His identity is inseparable from the cross.

Atonement and Worship

Seeing Jesus as the Lamb of God keeps the atonement at the center. His death wasn’t just a moral lesson—it was a substitution. The righteous for the unrighteous. That truth changes how we worship, how we repent, and how we walk with Him. It keeps us grounded in grace and aware of the cost of our redemption.

Living Under the Blood

We close with this—if you belong to Christ, you live under His blood. That means judgment has passed over you, mercy has been given to you, and grace is your standing place. And like we saw in The Lord’s Supper, every time we remember Him, we’re proclaiming His death until He comes. We live in the joy of His finished work and in the hope of seeing the Lamb face to face.
