What does the Bible say about why men are condemned?

According to John 3:18, men are condemned because they are not willing to believe in Jesus Christ, the only begotten Son of God. This condemnation is a result of their preference for darkness over light due to their evil deeds. The scripture reveals that the condemnation comes not from ignorance alone, but from a deliberate rejection of the truth found in Christ. Those who do not come to the light—who do not embrace the truth of the gospel—essentially love their sinful state and avoid exposure of their deeds by the light (John 3:19-20).
