'In the Light' in the Bible

while ye have the light, believe in the light, that ye may be the children of light. after having said these things, Jesus retir'd, and conceal'd himself from them.

but if we walk in the light, as he is in the light, we have society one with another, and the blood of his son Jesus Christ cleanseth us from all sin.

he that says, he is in the light, and yet hates his brother, is still in darkness.

he that loves his brother, abides in the light, and will be secure from stumbling.
