'Light' in the Bible

“The people who were sitting (living) in [spiritual] darkness have seen a great Light,And for those who were sitting (living) in the land and shadow of [spiritual and moral] death,Upon them a Light has dawned.”

“You are the light of [Christ to] the world. A city set on a hill cannot be hidden;

nor does anyone light a lamp and put it under a basket, but on a lampstand, and it gives light to all who are in the house.

Let your light shine before men in such a way that they may see your good deeds and moral excellence, and [recognize and honor and] glorify your Father who is in heaven.

“The eye is the lamp of the body; so if your eye is clear [spiritually perceptive], your whole body will be full of light [benefiting from God’s precepts].

But if your eye is bad [spiritually blind], your whole body will be full of darkness [devoid of God’s precepts]. So if the [very] light inside you [your inner self, your heart, your conscience] is darkness, how great and terrible is that darkness!

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 My yoke is easy [to bear] and My burden is light.”

And His appearance changed dramatically in their presence; and His face shone [with heavenly glory, clear and bright] like the sun, and His clothing became as white as light.

While he was still speaking, behold, a bright cloud overshadowed them, and a voice from the cloud said, “This is My beloved Son, with whom I am well-pleased and delighted! Listen to Him!”

But they paid no attention [they disregarded the invitation, treating it with contempt] and went away, one to his farm, another to his business.

“Teacher, which is the greatest commandment in the Law?”

“Immediately after the tribulation of those days the sun will be darkened, and the moon will not provide its light, and the stars will fall from the sky, and the powers of the heavens will be shaken.
