Give light, and the darkness will disappear of itself. (Desiderius Erasmus, 15th-16th century Dutch philosopher)

According to the Bible (John 3:19) men often prefer darkness to light because of their evil deeds. The only antidote for evil deeds (the Bible calls them sin) is the light of the truth. So, as Erasmus wrote, if we would shine that light of truth, we could overcome the darkness that we too often experience in modern society.

But those who do what is right come to the light so others can see that they are doing what God wants (John 3:21).
