1 John 3:5 → Isaiah 53:5

John's twofold statement — "Christ appeared to take away sins, and in Him there is no sin" — echoes the two defining notes of the Suffering Servant: he bears away the sins of others (53:5-6, 12, "He bore the sin of many") while being himself entirely without sin (53:9, "no deceit was found in His mouth"). The conjunction is the Servant Song's own logic: only the sinless one can be the sin-bearer. "To take away sins" (hina tas hamartias arē) recalls the sin-removal that runs through Isaiah 53 and that John the Baptist applied to Christ as the Lamb who "takes away the sin of the world" (John 1:29, itself rooted in Isa 53:7). John deploys the truth pastorally: because the sinless Servant came to remove sin, those abiding in him cannot make sin their settled way of life (3:6). The telos is not a moralizing ultimatum but the transforming sight of the sinless Sin-bearer: beholding the One who is pure and who carried away our impurity, the believer is drawn to purify himself "just as Christ is pure" (3:3) — holiness as the fruit of treasuring the spotless Servant, never its price.
