John 12:36

12:36 While you have the light, believe in the light, so that you may become sons of light.” When Jesus had said these things, he went away and hid himself from them.

John 12:46

12:46 I have come as a light into the world, so that everyone who believes in me should not remain in darkness.

tn The idiom “sons of light” means essentially “people characterized by light,” that is, “people of God.”

sn The expression sons of light refers to men and women to whom the truth of God has been revealed and who are therefore living according to that truth, thus, “people of God.”
