How do we know that Christ exposes the darkness of the world?

The Bible illustrates this concept in John 3:19, where it states that people reject the light of Christ because they fear their evil deeds will be exposed. This reality highlights the nature of sin — individuals are inherently inclined to hide from the truth that Christ brings. Jesus testifies to the world's wickedness, and in doing so, He becomes a problem for humanity, which desires to continue in its sinful ways without the confrontation of truth. Therefore, His role as the light exposes the darkness and reveals anyone's unwillingness to confront their sinfulness.
