For once you were darkness, but now you are light in the Lord; walk as children of Light [live as those who are native-born to the Light]

Do not participate in the worthless and unproductive deeds of darkness, but instead expose them [by exemplifying personal integrity, moral courage, and godly character];

For our struggle is not against flesh and blood [contending only with physical opponents], but against the rulers, against the powers, against the world forces of this [present] darkness, against the spiritual forces of wickedness in the heavenly (supernatural) places.

so that you may prove yourselves to be blameless and guileless, innocent and uncontaminated, children of God without blemish in the midst of a [morally] crooked and [spiritually] perverted generation, among whom you are seen as bright lights [beacons shining out clearly] in the world [of darkness],

The Incomparable Christ

For He has rescued us and has drawn us to Himself from the dominion of darkness, and has transferred us to the kingdom of His beloved Son,

But you, believers, [all you who believe in Christ as Savior and acknowledge Him as God’s Son] are not in spiritual darkness [nor held by its power], that the day [of judgment] would overtake you [by surprise] like a thief;

for you are all sons of light and sons of day. We do not belong to the night nor to darkness.

For you have not come [as did the Israelites in the wilderness] to a mountain that can be touched and to a blazing fire, and to gloom and darkness and a raging windstorm,

But you are a chosen race, a royal priesthood, a consecrated nation, a [special] people for God’s own possession, so that you may proclaim the excellencies [the wonderful deeds and virtues and perfections] of Him who called you out of darkness into His marvelous light.

These [false teachers] are springs without water and mists driven by a tempest, for whom is reserved the gloom of black darkness.

God Is Light

This is the message [of God’s promised revelation] which we have heard from Him and now announce to you, that God is Light [He is holy, His message is truthful, He is perfect in righteousness], and in Him there is no darkness at all [no sin, no wickedness, no imperfection].

If we say that we have fellowship with Him and yet walk in the darkness [of sin], we lie and do not practice the truth;

On the other hand, I am writing a new commandment to you, which is true and realized in Christ and in you, because the darkness [of moral blindness] is clearing away and the true Light [the revelation of God in Christ] is already shining.

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.

But the one who habitually hates (works against) his brother [in Christ] is in [spiritual] darkness and is walking in the darkness, and does not know where he is going because the darkness has blinded his eyes.

And angels who did not keep their own designated place of power, but abandoned their proper dwelling place, [these] He has kept in eternal chains under [the thick gloom of utter] darkness for the judgment of the great day,

wild waves of the sea, flinging up their own shame like foam; wandering stars, for whom the gloom of deep darkness has been reserved forever.

Then the fifth angel poured out his bowl on the throne of the beast, and his kingdom was plunged into darkness; and people gnawed their tongues because of the pain [of their excruciating anguish and severe torment],
