Contradiction with John 8:12
John 8:12 states that Jesus is the light of the world, making it exclusive to Him, while John 1:9 refers to a light that lights every man, suggesting a more universal application.
John 8:12: Then spake Jesus again unto them, saying, I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life.
Contradiction with Matthew 5:14
Matthew 5:14 indicates that followers are the light of the world, which contrasts with the notion in John 1:9 of a singular true light.
Matthew 5:14: Ye are the light of the world. A city that is set on an hill cannot be hid.
Contradiction with 1 John 2:8
1 John 2:8 mentions that the true light is now shining, implying an ongoing or present action, whereas John 1:9 suggests a past action that "was the true Light."
1 John 2:8: Again, a new commandment I write unto you, which thing is true in him and in you: because the darkness is past, and the true light now shineth.
Contradiction with 2 Corinthians 4:4
2 Corinthians 4:4 speaks of the gospel being veiled to those who are perishing, suggesting not everyone is illuminated by the light, in contrast to John 1:9 which indicates the light enlightens every man.
2 Corinthians 4:4: In whom the god of this world hath blinded the minds of them which believe not, lest the light of the glorious gospel of Christ, who is the image of God, should shine unto them.
Paradox #1
Some people might see a contradiction in the idea of spiritual enlightenment being available to everyone, while other parts of the Bible suggest that only certain people are chosen or predestined for salvation. This can lead to debates about free will versus predestination in Christian theology.
