Ephesians 5:8

8. Ye were While Gentiles.

Now are ye light Not as illuminated, but as luminous and illuminating. So our Saviour: “Ye are the light of the world.”

Children of light In the whole paragraph there is a blending of the double thought of moral and physical light. So our Lord: “Let your light so shine, that men may see your good works.” The children of light are those who are not only the true sons of moral illumination, but are so congenial with the actual light of day that the sun may freely shine upon all they do, and illuminate even the secrets locked within their breasts. And so, also, in the uses of both the terms light and darkness there is a blended double reference to the moral principles and the classes of men who embody the principles. Christians are light, and they are children of light; and, Ephesians 5:13, the darkness of the licentious, by having the light shine through them, becomes light.
