John 8 - ESV Gospel Transformation Study Bible

8:12–20 In his prologue, John has already identified Jesus as the source of life and the “light of men” (1:4)—the light for which the darkness is no match (1:5). Thus we should not be surprised that Jesus includes “I am the light of the world” (8:12) among his seven “I am” affirmations. Indeed, Jesus is the incarnation of the “true light” (1:9), alone sufficient to rescue any man, any time, from the darkness of sin and death. He who is affirmed as the Creator of light (1:3) came as the light of redemption. The prophet Isaiah envisioned the work of the Messiah, God’s servant, as the one who would be revealed as a “light for the nations, that my salvation may reach to the end of the earth” (Isa. 49:6).

The sinfulness of sin is seen in the reality that “people loved the darkness rather than the light” (John 3:19). Yet Jesus came to be lifted up on the cross so that we who “believe in the light” might become “sons of light” (12:32–36)—so great is his grace, so great is his gospel. Jesus took the darkness of God’s judgment so that we might now receive the light of God’s salvation. The Old Testament concludes with the hope of a day in which “the sun of righteousness shall rise with healing in its wings” (Mal. 4:2). As God’s beloved Son, Jesus is that risen sun. He is our healing because he is our righteousness.

In his last chronicled writing, John saw the day in which the Lamb of God, the Lord of lords, would be extolled as the lamp of the eternal city, the new Jerusalem: “The city has no need of sun or moon to shine on it, for the glory of God gives it light, and its lamp is the Lamb” (Rev. 21:23). How we long for that day of perfect love and unfiltered light.

8:21–30 The hostile reaction of the Pharisees to Jesus’ words is understandable, but rather than backing down, Jesus intensifies his claims. The accused now becomes the accuser—the witness takes the role of prosecuting attorney. Jesus is from above, they are from below; they are of this world, Jesus is not of this world. They charged Jesus with sin; they will remain in their sins unless they believe on him.

The gospel is an unrelenting assault on graceless religion, on all the ways we try to avoid grace. It is also a powerful demonstration of the sovereignty of God. In that very unlikely moment, many believed in Jesus. God can save anyone, anytime, anywhere. He is not constrained by human intuitions about who is really “save-able.” Grace confounds our law-saturated, self-accomplishing expectations of what activates divine mercy.

8:31–59 Jesus promises a freedom that no one else can give based on truth that he alone possesses. As the Messiah, he has come to set prisoners free (Luke 4:16–21; Isa. 61:1–3). True freedom can be found only in the “right paternity”: not everyone who claims Abraham as their father has God as their Father, “for not all who are descended from Israel belong to Israel” (Rom. 9:6). None can claim God as their Father who won’t have his Son as their Savior.

If our spiritual genealogy includes only our earthly heritage (as was true of the “children of Abraham” in this passage), we may be religious, but we are still spiritual orphans. True spiritual heritage requires a connection to one who existed long before Abraham, namely, Jesus: “before Abraham was, I am” (John 8:58). Only through the gospel can we be rescued from the dominion of darkness (Col. 1:13), where Satan is father, and be brought into the family of God, where we are given the full rights and delights of the children of God (John 1:12; Gal. 4:5; 1 John 3:1–3).
