“But he who does the truth comes to the light, that his deeds may be clearly seen, that they have been done in God.” – John 3:21
D.A. Carson calls this person the “light-lover.” He is contrasted with the light-hater in verse 20.
This weird phrasing means the person who is living biblically comes to the light, not out of pride or arrogance, but to exalt God. It’s to glorify the Creator, not Self.
Doing the truth is done in light of God’s sovereignty.
