'In the Light' in the Bible

What I am telling you in the darkness [i.e., in obscurity], you tell it in the light [i.e., openly]. And what you hear [whispered] in your ear [you should] declare it from the housetops.

Therefore, whatever you have said in the darkness [i.e., in obscurity] will be heard in the light [i.e., openly]. And what you have whispered in someone's ear in a back room, will be declared from the housetops.

Then a certain [servant] girl saw Peter sitting there in the light of the fire. As she stared at him she said, "This man was with Jesus, too."

[So], believe in the Light [i.e., Jesus is speaking of Himself] while you [still] have the Light [with you], so that you can become enlightened people." After Jesus said these things, He left there and hid Himself from them.

But, if we live in the light [of righteousness] just like God [constantly] lives in the light [of righteousness], we can truly share a relationship with one another and [can know that] the blood of Jesus, God's Son, continues to cleanse [our spirits] from all of our sins.
