Exegesis of John 8:12

1. "I Am the Light of the World"

• Matthew Henry emphasizes that the designation "I am the light" alludes to the divine nature of Christ, mirroring the Old Testament references where God is described as light (Psalm 27:1; Isaiah 60:19).
• Albert Barnes contemplates the universality of this light, noting that Christ’s light is not limited to a specific group but extends to the entire world, offering salvation freely to all who believe.
• Adam Clarke asserts that this declaration is filled with profound theological insight; Jesus as light symbolizes purity, knowledge, and truth, standing in contrast to the moral darkness of the world.

2. "He that Followeth Me"

• Matthew Henry focuses on the imperative action of 'following.' To follow Christ means to embrace His teachings and to live a life reflective of His guidance, which leads believers out of moral and spiritual darkness.
• Albert Barnes points out the importance of commitment and discipleship inherent in this phrase. Following Christ is an active and continuous pursuit that requires dedication to His example and teachings.
• Adam Clarke highlights that following Christ entails more than mere belief; it requires a transformation of life and an active separation from the darkness of sin.

3. "Shall Not Walk in Darkness"

• Matthew Henry interprets 'darkness' as emblematic of sin, ignorance, and separation from God. Those who truly follow Christ are promised freedom from these spiritual chains.
• Albert Barnes explains that 'walking' implies a lifestyle or habitual conduct. Therefore, those who follow Jesus will no longer live in the ways of the world that lead to despair and confusion.

• Albert Barnes explains this phrase as a promise of both illumination in this life and the assurance of eternal life, encompassing the fullness of spiritual understanding and righteousness.
• Adam Clarke expands on the significance of 'light of life,' linking it to salvation, spiritual vitality, and the transformative power of Christ's grace within believers.
