The next day John saw Jesus coming to him and said, Look! There is the Lamb of God, Who takes away the sin of the world! John 1:29 AMP

Jesus was the Perfect Lamb, sacrificed just like the unblemished Passover lamb, but whose blood was shed once and for all. There is no need for any other sacrifice, for Jesus made the ultimate sacrifice and paid the ultimate price. He will forever be the Lamb of God, taking away the sin of the world.

Christ, the Sacrificial Lamb:

He was oppressed and He was afflicted, Yet He opened not His mouth; He was led as a lamb to the slaughter, And as a sheep before its shearers is silent, So He opened not His mouth. Isaiah 53:7 NKJV

The place in the Scripture which he read was this: “He was led as a sheep to the slaughter; And as a lamb before its shearer is silent, So He opened not His mouth. Acts 8:32 NKJV

Knowing that you were not redeemed with corruptible things, like silver or gold, from your aimless conduct received by tradition from your fathers, 19 but with the precious blood of Christ, as of a lamb without blemish and without spot. 1 Peter 1:18-19 NKJV

The Lamb who, by His blood, takes away the sin of the world:

“Takes away”: Greek: “airo” meaning: to bear in the sense of removing sin; doing away with the guilt and punishment. Sin: Greek “hamartia” meaning: a sin; offence, sinful.

Who his own self bare our sins in his own body on the tree, that we, being dead to sins, should live unto righteousness: by whose stripes ye were healed. 1 Peter 2:24 KJV

As far as the east is from the west, so far has He removed our transgressions from us. Psalms 103:12 AMP

And you know that He was manifested to take away our sins, and in Him there is no sin. 1 John 3:5 NKJV

The Lamb who takes away our sin and who empowers us to walk in righteousness and to do right:

For the grace of God that brings salvation has appeared to all men, 12 teaching us that, denying ungodliness and worldly lusts, we should live soberly, righteously, and godly in the present age, 13 looking for the blessed hope and glorious appearing of our great God and Savior Jesus Christ, 14 who gave Himself for us, that He might redeem us from every lawless deed and purify for Himself His own special people, zealous for good works. Titus 2:11-14 NKJV

My little children, these things I write to you, so that you may not sin. And if anyone sins, we have an Advocate with the Father, Jesus Christ the righteous. 2 And He Himself is the propitiation for our sins, and not for ours only but also for the whole world. 1 John 2:1-2 NKJV

If you know that He is righteous, you know that everyone who practices righteousness is born of Him. 1 John 2:29 NKJV

Whoever has been born of God does not sin, for His seed remains in him; and he cannot sin, because he has been born of God. 1 John 3:9 NKJV

Whoever believes that Jesus is the Christ is born of God, and everyone who loves Him who begot also loves him who is begotten of Him. 2 By this we know that we love the children of God, when we love God and keep His commandments. 3 For this is the love of God, that we keep His commandments. And His commandments are not burdensome. 4 For whatever is born of God overcomes the world. And this is the victory that has overcome the world — our faith. 1 John 5:1-4 NKJV

We know that whoever is born of God does not sin; but he who has been born of God keeps himself, and the wicked one does not touch him. 1 John 5:18 NKJV

Worthy is the Lamb who was slain – to rule and to reign and to receive worship and honor throughout all eternity:

Then I looked, and I heard the voice of many angels around the throne, the living creatures, and the elders; and the number of them was ten thousand times ten thousand, and thousands of thousands, 12 saying with a loud voice: “Worthy is the Lamb who was slain To receive power and riches and wisdom, And strength and honor and glory and blessing!” Revelation 5:11-12 NKJV

After these things I looked, and behold, a great multitude which no one could number, of all nations, tribes, peoples, and tongues, standing before the throne and before the Lamb, clothed with white robes, with palm branches in their hands, 10 and crying out with a loud voice, saying, “Salvation belongs to our God who sits on the throne, and to the Lamb!” Revelation 7:9-10 NKJV

And they overcame him by the blood of the Lamb and by the word of their testimony, and they did not love their lives to the death. Revelation 12:11 NKJV

These will make war with the Lamb, and the Lamb will overcome them, for He is Lord of lords and King of kings; and those who are with Him are called, chosen, and faithful. Revelation 17:14 NKJV

And he showed me a pure river of water of life, clear as crystal, proceeding from the throne of God and of the Lamb. 2 In the middle of its street, and on either side of the river, was the tree of life, which bore twelve fruits, each tree yielding its fruit every month. The leaves of the tree were for the healing of the nations. 3 And there shall be no more curse, but the throne of God and of the Lamb shall be in it, and His servants shall serve Him. Revelation 22:1-3 NKJV
