'In the Light' in the Bible

What I tell you in the darkness, speak ye in the light, and what ye hear in the ear, proclaim upon the housetops.

Therefore, as many things as ye have said in the darkness will be heard in the light, and what ye have spoken in the ear in the inner chambers will be proclaimed upon the housetops.

While ye have the light, believe in the light, so that ye may become sons of light. Jesus spoke these things, and after departing, he was hid from them.

But if we walk in the light, as he is in the light, we have fellowship with each other, and the blood of Jesus Christ his Son cleanses us from every sin.

He who claims to be in the light, and hates his brother, is in the darkness until now.

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