'Children of Light' in the Bible

And the lord praised the unjust steward, because he did wisely; for the children of this life are wiser, for their generation, than the children of light.

While you have the light, believe in the light, that you may be children of light. Jesus said these things, and went away and concealed himself from them.

For you were formerly darkness, but now you are light in the Lord. Walk as children of light,??9 for the fruit of the light is in all goodness and righteousness and truth,??10 proving what is well pleasing to the Lord,

for you are all children of light, and children of day; we are not of night nor of darkness.
