'In the Light' in the Bible

What I say unto you in the darkness, speak ye in the light: and whatsoever you hear in the ear, proclaim upon the housetops.

Therefore so many things as you spoke in the darkness shall be heard in the light; and whatsoever you spoke in the ear in the secret chambers shall be proclaimed upon the houses.

While you have the light, believe in the light, in order that you may be the sons of light. And Jesus spoke these things, and having gone out was hidden 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.

The one saying that he is in the light, and hating his brother, is in the darkness until now.

The one loving his brother with divine love abides in the light, and there is no stumbling in him.
