John 1:29
John 1:2929The next day John saw Jesus coming toward him and said, “Look, the Lamb of God, who takes away the sin of the world!
Read as identifying Jesus as the perfect-human ransom — the "corresponding ransom" of JW soteriology. The Lamb who takes away sin is read as a perfect human exactly equivalent to the perfect human Adam who lost everything; the ransom is exact equivalence, not infinite worth.
Pair with , 15 in the JW's own NWT — "not one of them can ever redeem a brother... the redemption price of their life is so precious that it is always beyond their reach... but God will redeem my life from Sheol." The psalm establishes that no man can pay the redemption price. If Jesus is only a perfect man, cannot be true: the Lamb cannot take away the sin of the world if the redeemer is what Psalm 49 says no man can be. Pair with — Christ obtained "everlasting deliverance" through "an everlasting spirit," not as one more Levitical sacrifice. The "how much more" logic of depends on Christ being categorically superior to bulls and goats, not just a better human specimen.
