'In the Light' in the Bible

What I say to you in the dark (privately), tell in the light (publicly); and what you hear whispered in your ear, proclaim from the housetops [to many people].

For that reason, whatever you have said in the dark will be heard in the light, and what you have whispered behind closed doors will be proclaimed on the housetops.

While you have the Light, believe and trust in the Light [have faith in it, hold on to it, rely on it], so that you may become sons of Light [being filled with Light as followers of God].”Jesus said these things, and then He left and hid Himself from them.

giving thanks to the Father, who has qualified us to share in the inheritance of the saints (God’s people) in the Light.

I solemnly charge you in the presence of God and of Christ Jesus, who is to judge the living and the dead, and by His appearing and His kingdom:

but if we [really] walk in the Light [that is, live each and every day in conformity with the precepts of God], as He Himself is in the Light, we have [true, unbroken] fellowship with one another [He with us, and we with Him], and the blood of Jesus His Son cleanses us from all sin [by erasing the stain of sin, keeping us cleansed from sin in all its forms and manifestations].

The one who says he is in the Light [in consistent fellowship with Christ] and yet habitually hates (works against) his brother [in Christ] is in the darkness until now.

The one who loves and unselfishly seeks the best for his [believing] brother lives in the Light, and in him there is no occasion for stumbling or offense [he does not hurt the cause of Christ or lead others to sin].
