'In the Light' in the Bible

"What I tell you in darkness, speak in the light: and what you hear in the ear, preach on the house-tops.

Wherefore, what you have spoken in the darkness, shall be heard in the light; and what you have spoken in the ear in closets, shall be proclaimed upon the house-tops.

While you have the light, believe in the light, that you may become the sons of light. These things spoke Jesus, and he departed, and concealed himself from them.

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

He that says he is in the light, and hates his brother, is in darkness till now.

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