3 Bible Verses about Light And Darkness

Do not enter into inconsistent relations with those who reject the Faith. For what partnership can there be between righteousness and lawlessness? or what has light to do with darkness?

And still stronger is the assurance that we have in the teaching of the Prophets; to which you will do well to pay attention (as if it were a lamp shining in a gloomy place), until the Day dawns and the Morning Star rises in your hearts.

He who says that he is in the Light, and yet hates his Brother, is in the Darkness even now.
