John 1:29; Hebrews 9:13-15; Revelation 5:11-14

John 1:29

29 The next day he saw Jesus coming toward him, and said, "Behold, the Lamb of God, who takes away the sin of the world!

Hebrews 9:13-15

13 For if the blood of goats and bulls, and the sprinkling of defiled persons with the ashes of a heifer, sanctify for the purification of the flesh,

14 how much more will the blood of Christ, who through the eternal Spirit offered himself without blemish to God, purify our conscience from dead works to serve the living God.

15 Therefore he is the mediator of a new covenant, so that those who are called may receive the promised eternal inheritance, since a death has occurred that redeems them from the transgressions committed under the first covenant.

Revelation 5:11-14

11 Then I looked, and I heard around the throne and the living creatures and the elders the voice of many angels, numbering myriads of myriads and thousands of thousands,

12 saying with a loud voice, "Worthy is the Lamb who was slain, to receive power and wealth and wisdom and might and honor and glory and blessing!"

13 And I heard every creature in heaven and on earth and under the earth and in the sea, and all that is in them, saying, "To him who sits on the throne and to the Lamb be blessing and honor and glory and might forever and ever!"

14 And the four living creatures said, "Amen!" and the elders fell down and worshiped.
