Expositor's Bible Commentary Commentary John 3:21

"But he that doeth the truth cometh to the light, that his works may be made manifest, that they have been wrought in God." — John 3:21 (ASV)

The difference between believers and unbelievers does not lie in the guilt or innocence of either; it lies in the different attitudes they take toward the “light.” Unbelievers shrink from the light because it exposes their sin; believers willingly come to the light so that their real motives may be revealed (see also 1Jn 1:8-9). Furthermore, darkness (defined as love of evil deeds) keeps people from responding to the light . All of us are held accountable for our actions, and the choice is ours: evil deeds or truth.
