Summary: A brief review of the texts in the Revelation of Jesus Christ recording the word "Lamb"
The Lamb of God
The Lord Jesus Christ is the main Person of the Apocalypse with His preferred title the "Lamb" appearing (28) times in the book of the Revelation. Although John in Revelation 1-3 sees him as the glorified Lord of glory, the first appearance of the Lord as the “Lamb” occurs at Revelation 5:6-8 where He is introduced in the throne room of God at His heavenly coronation:
"And I beheld, and, lo, in the midst of the throne and of the four beasts, and in the midst of the elders, stood a Lamb as it had been slain, having seven eyes, which are the seven Spirits of God sent forth into all the earth. And He came and took the book out of the right hand of Him that sat upon the throne. And when He had taken the book, the four beasts and four and twenty elders fell down before the Lamb having every one of them harps and golden vials full of odors, which are the prayers of the saints."
The magnificent praise and worship scene that follows in 5:9-14 reveals that this is the main event of the Apocalypse as the Lord Jesus Christ, the Lord of Glory, is the only One worthy to take the scroll from the Father which begins end-time events on planet earth.
The Lord Jesus, who alone is the Righteous Judge (John 5:27-29), is now prepared to loose the seals on the outside of the scroll in order to begin the events of the 70th Week of Daniel. It is only as the Lord Jesus starts the unfolding of events at the end of the age that "the things which shall be hereafter" (Revelation 1:19) will occur in His perfect timing and sovereign control.
Now it is His day that is about to happen, for the LORD Jehovah is making the enemies of the Lord Jesus Christ "His footstool" (Psalm 110:1) and the time has now come for God the Father to bring this promise He made to the Lord Jesus Christ to complete fruition.
At the end of this glorious praise scene in Revelation 5:9-14, which occurs in heaven, the time-clock of the end times begins to tick as “the Lamb” opens the seals on the outside of the scroll He has just taken from God the Father’s hand:
"And I saw when the Lamb opened one of the seals, and I heard, as it were the noise of thunder, one of the four beasts saying, Come and see. And I saw, and behold a white horse: and he that sat on him had a bow; and a crown was given unto him; and he went forth conquering and to conquer." (Revelation 6:1, 2)
The Lamb who is in complete control of the events of the 70th Week of Daniel, allows the Antichrist to begin conquering when he will "subdue three kings" (Daniel 7:24, 7:20, 7:8) of "the ten kings that shall arise" (Daniel 7:24; Revelation 17:12) in that day.
The next time “the Lamb” is mentioned occurs in Revelation 6:16, 17:
"And said to the mountains and rocks, Fall on us, and hide us from the face of Him that sits on the throne, and from the wrath of the Lamb: For the great day of His wrath is come; and who shall be able to stand?"
After the events which occur from the opening of the first five seals by the Lamb, the opening of the sixth seal causes the men of the earth to recognize that God is about to send His Day of the Lord judgment from heaven. They realize that no one will be able to bear the Lamb’s great wrath. Then, after the sealing of the 144 Thousand (Revelation 7:1-8), the Lamb appears "before the throne" in heaven as the resurrected and raptured saints arrive in heaven:
