'In the Light' in the Bible

What I tell you in the dark, speak in the light; and what you hear whispered in your ear, proclaim on the housetops.

Therefore whatever you have said in the dark will be heard in the light, and what you have whispered in the ear in the inner rooms will be proclaimed from the housetops.

While you have the light, believe in the light, that you may become sons of light." When Jesus had said this, he departed and hid himself from them.

But if we walk in the light, as he is in the light, we have fellowship with one another, and the blood of Jesus his Son cleanses us from all sin.

He who says he is in the light and hates his brother is in the darkness still.

He who loves his brother abides in the light, and there is no cause for stumbling in him.
