The next day he saw Jesus coming toward him, and said, “Behold, the Lamb of God, who takes away the sin of the world! (John 1:29 ESV)
(For a better and more recent defense see here.)
Those who advocate the doctrine of Unlimited Atonement obviously take “world” everyone who has lived or will live, all without exception. Not world in the sense of many people, not world in the sense of from every “tribe and language and people and nation” as Revelation 5:9 would put it
Here is what the ESV MacArthur Study Bible says: [1]
John 1:29 The next day. This phrase probably refers to the day after John’s response to the Jerusalem delegation. It also initiates a sequence of days (v. 43; 2:1) that culminated in the miracle at Cana (2:1–11). the Lamb of God. The use of a lamb for sacrifice was very familiar to Jews. A lamb was used as a sacrifice during Passover (Ex. 12:1–36); a lamb was led to the slaughter in the prophecies of Isaiah (Isa. 53:7); a lamb was offered in the daily sacrifices of Israel (Lev. 14:12–21; cf. Heb. 10:5–7). John the Baptist used this expression as a reference to the ultimate sacrifice of Jesus on the cross to atone for the sins of the world, a theme which John the apostle carries throughout his writings (John 19:36; cf. Rev. 5:1–6; 7:17; 17:14) and that appears in other NT writings (e.g., 1 Pet. 1:19). sin of the world! See note on John 1:9; cf. 3:16; 6:33, 51. In this context “world” has the connotation of humanity in general, not specifically every person. The use of the singular “sin” in conjunction with “of the world” indicates that Jesus’ sacrifice for sin potentially reaches all human beings without distinction (cf. 1 John 2:2). John makes clear, however, that its efficacious effect is only for those who receive Christ (John 1:11–12). For discussion of the relation of Christ’s death to the world, see note on 2 Cor. 5:19.
The following is said by John Gill:[2]
- and saith, behold the Lamb of God, which taketh away the sin of the world: he calls him a "lamb", either with respect to any lamb in common, for his harmlessness and innocence; for his meekness and humility; for his patience; and for his usefulness, both for food and clothing, in a spiritual sense; as well as for his being to be a sacrifice for the sins of his people: or else with respect to the lambs that were offered in sacrifice, under the legal dispensation; and that either to the passover lamb, or rather to the lambs of the daily sacrifice, that were offered morning and evening; since the account of them best agrees with what is said of this Lamb of God, who was slain in type, in the morning of the world, or from the foundation of the world; and actually in the evening of the world, or in the end of it; and who has a continued virtue to take away the sins of his people, from the beginning, to the end of the world; and their sins, both of the day and night, or which are committed every day: for as they are daily committed, there is need of the daily application of the blood and sacrifice of Christ, to remove them; or of continual looking unto him by faith, whose blood has a continual virtue, to cleanse from all sin: the Jewish doctors say {d}, that
- "the morning daily sacrifice made atonement for the iniquities done in the night; and the evening sacrifice made atonement for the iniquities that were by day:''
- and in various things they were typical of Christ, as that they were lambs of the first year, which may denote the...
