3 Bible Verses about Light And Darkness

Be not unequally yoked with unbelievers; for what fellowship has righteousness with lawlessness? what communion has light with darkness?

And so we possess the word of prophecy made yet more sure. Unto this you do well to give heed as to a lamp shining in a dark place, till the day dawns and the morning star rises in your hearts.

He who says he is in the light, and hates his brother, is in darkness even until now.
