The Central Idea of the Text is that Jesus reveals He has come from heaven as the Light of the world to offer life to those who believe in Him. Jesus revealed Himself as the Light of the world (John 8:12; cf. 1:4, 9; 12:35, 46). Darkness is a picture of spiritual blindness, evil, and rebellion against God (John 1:4-5; 3:19). Light is a picture of God’s life and holiness (John 1:4; 1 John 1:5). To follow Jesus means we believe in Him as Savior (John 3:16), and learn to walk as children of Light (Eph. 5:8-10). The hostile Pharisees accused Jesus of testifying about Himself (John 8:13), but Jesus revealed His testimony is true (John 8:14-15), and that God the Father also testifies about Him (John 8:18). John reveals the Pharisees did not understand Jesus’ words (John 8:19, 27). Jesus said these things in the temple (John 8:20), and revealed to His hearers they would die in their sin unless they believed in Him (John 8:21-24). Jesus’ hearers would know His claims to be true at the cross (John 8:26-28). Finally, Jesus revealed His Father was always with Him and that Jesus always pleased Him (John 8:29).
