Being in darkness is lost
Luke 11:33-36
“No one lights a lamp and puts it in a place where it will be hidden, or under a bowl. Instead he puts it on its stand, so that those who come in may see the light. Your eye is the lamp, of your body. When your eyes are good, your whole body also is full of light. But when they are bad, your body also is full of darkness. See to it, then, that the light within you is not darkness. Therefore, if your whole body is full of light, and no part of it is dark, it will be completely lighted, as when the light of a lamp shines on you.”
Luke 16:8
“The master commended the dishonest manager because he had acted shrewdly. For the people of this world are more shrewd in dealing with their own kind than are the people of the light.”
John 3:19-21
“This is the verdict: Light has come into the world, but men loved darkness instead of the light because their deeds were evil. Everyone who does evil hates the light, and will not come into the light for fear that his deeds will be exposed. But whoever lives by the truth comes into the light, so that it may be seen plainly that what he has done has been done through God.”
John 8:12
“When Jesus spoke again to the people, He said, ‘I am the light of the world. Whoever follows Me will never walk in darkness, but will have the light of life.”
John 12:35-36
“Then Jesus told them, ‘You are going to have the light just a little while longer. Walk while you have the light, before darkness overtakes you. The man who walks in the dark does not know where he is going. Put your trust in the light while you have it, so that you may become sons of light.”
Acts 26:17-18
(Jesus speaking to Paul on the Damascus Road)
“I will rescue you from your own people and from the Gentiles. I am sending you to open their eyes and turn them from darkness to light, and from the power of Satan to God, so that they may receive forgiveness of sins and a place among those who are sanctified by faith in Me.”
Romans 1:21-23
“For although they knew God, they neither glorified Him as God nor gave thanks to Him, but their thinking became futile and their foolish hearts were darkened. Although they claimed to be wise, they became fools and exchanged the glory of the immortal God for images made to look like mortal man and birds and animals and reptiles.”
Romans 13:12-14
“The night is nearly over, the day is almost here. So let us put aside the deeds of darkness and put on the armor of light. Let us behave decently, as in the daytime, not in orgies and drunkenness, not in sexual immorality and debauchery, not in dissension and jealousy. Rather, clothe yourselves with the Lord Jesus Christ, and do not think about how to gratify the desires of the flesh.”
2 Corinthians 4:3-6
“And even if our gospel is veiled, it is veiled to those who are perishing. The god of this world has blinded the minds of the unbelievers, so that they cannot see the light of the glory of Christ, who is the image of God. For we do not preach ourselves, but Jesus Christ as Lord, and ourselves as your servants for Jesus’ sake. For God, who said, ‘Let light shine out of darkness,’ has made His light shine in our hearts to give us the light of the knowledge of the glory of God in the face of Christ.”
2 Corinthians 6:14-16
“Do not be yoked together with unbelievers. For what do righteousness and unrightsousness have in common? Or what fellowship can light have with darkness? What harmony is there between Christ and Belial? What does a believer have in common with an unbeliever? What agreement is there between the temple of God and idols? For we are the temple of the living God. As God has said: ‘I will live with them and walk among them, and I will be their God, and they will be My people.”
Ephesians 4:17-18
“So I tell you this, and insist on it in the Lord, that you must no longer live as the Gentiles do, in the futility of their thinking. They are darkened in their understanding and separated from the life of God because of the ignorance that is in them due to the hardening of their hearts.”
Ephesians 5:8-14
“For you were once darkness, but now you are light in the Lord. Live as children of light (for the fruit of the light consists in all goodness, righteousness and truth) and find out what pleases the Lord. Have nothing to do with the fruitless deeds of darkness, but rather expose them. For it is shameful even to mention what the disobedient do in secret. But everything exposed by the light becomes visible, for it is light that makes everything visible. This is why it is said. ‘Wake up, 0 sleeper, rise from the dead, and Christ will shine on you.”
Ephesians 6:12
“For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms.”
Colossians 1:12-13
“…the Father, who has qualified you to share in the inheritance of the saints in light. For He has rescued us from the dominion of darkness and brought us into the kingdom of the Son He loves, in whom we have redemption, the forgiveness of sins.”
Thessalonians 5:4-9
“But you, brothers, are not in darkness so that this day should surprise you like a thief. You are all sons of the light and sons of the day. We do not belong to the night or to the darkness. So then, let us not be like the others, who are asleep, but let us be alert and self-controlled. For those who sleep, sleep at night, and those who get drunk, get drunk at night. But since we belong to the day, let us be self-controlled, putting on faith and love as a breastplate, and the hope of salvation as a helmet. For God did not appoint us to suffer wrath, but to receive salvation through our Lord Jesus Christ.”
Timothy 6:15b-16
“God, the blessed and only Ruler, the King of kings and Lord of lords, who alone is immortal and who lives in unapproachable light, whom no one has ever seen or can see. To Him be honor and might forever. Amen.”
Peter 2:9
“But you are a chosen people, a royal priesthood, a holy nation, a people belonging to God, that you may declare the praises of Him who called you out of darkness into His wonderful light.”
I John 1:5-7
“This is the message we have heard from Him and declare to you: God Is light, In Him there Is no darkness at all. If we claim to have fellowship with Him yet walk in darkness, we lie and do not live by the truth. But if we walk in the light, as He is in the light, we have fellowship with one another, and the blood of Jesus, His Son, purifies us from every sin.”
I John 2:8-11
“Yet I am writing you a new command, its truth is seen in Him and you, because the darkness is passing and the true light is already shining. Anyone who claims to be in the light but hates his brother is still in the darkness. Whoever loves his brother lives in the light, and there is nothing in him to make him stumble. But whoever hates his brother is in the darkness and walks around in darkness; he does not know where he is going, because the darkness has blinded him.”
