Concise Bible Dictionary:
The lamb is symbolical of meek submissiveness, and when selected for the sacrifices, must be without blemish and without spot: a very apt type of the Lord Jesus, the Lamb of God. He, the submissive and spotless One, was “like a lamb dumb before his shearer,” and was proclaimed by John as “the Lamb of God which taketh away the sin of the world”; and again as “the Lamb of God” as an object for the soul’s contemplation (John 1:29,36). In John’s vision of heaven the Lord Jesus is seen as a Lamb “which had been slain,” to whom universal adoration is given.
The special character attached to the title of “Lamb” in the book of Revelation is that of suffering, the earth-rejected One, but seen in the midst of the throne in heaven. He who suffered is vindicated there, and finally possesses His bride, the new Jerusalem, in which the throne of God and of the Lamb is established. He will always bear the character of the chosen One of God “that taketh away the sin of the world” on the ground of the sacrifice of Himself (Rev. 5:6-13; Rev. 6:1,16; Rev. 7:9-17; Rev. 12:11; Rev. 14:1-10; Rev. 15:3; Rev. 17:14; Rev. 19:7,9; Rev. 21:9-27; Rev. 22:1,3). In all these passages in the Revelation the word is ἀρνίον, the diminutive of ἀρνός, “a lamb,” signifying a “young lamb,” or “lambkin.” The same word was used by the Lord to Peter in John 21:15: “Feed My lambs,” applying it to the Lord’s young disciples.
