11 Bible Verses on Demon Appearance

And no wonder, for Satan himself masquerades as an angel of light.

Beloved, do not believe every spirit, but test the spirits to see whether they are from God. For many false prophets have gone out into the world.

Then I saw a beast with ten horns and seven heads rising out of the sea. There were ten royal crowns on its horns and blasphemous names on its heads. The beast I saw was like a leopard, with the feet of a bear and the mouth of a lion. And the dragon gave the beast his power and his throne and great authority. One of the heads of the beast appeared to be mortally wounded. But the mortal wound was healed, and the whole world marveled and followed the beast. They worshiped the dragon who had given authority to the beast, and they worshiped the beast, saying, “Who is like the beast, and who can wage war against it?” The beast was given a mouth to speak arrogant and blasphemous words, and authority to act for 42 months. And the beast opened its mouth to speak blasphemies against God and to slander His name and His tabernacle—those who dwell in heaven. Then the beast was permitted to wage war against the saints and to conquer them, and it was given authority over every tribe and people and tongue and nation. And all who dwell on the earth will worship the beast—all whose names have not been written from the foundation of the world in the Book of Life belonging to the Lamb who was slain. He who has an ear, let him hear: “If anyone is destined for captivity, into captivity he will go; if anyone is to die by the sword, by the sword he must be killed.” Here is a call for the perseverance and faith of the saints. Then I saw another beast rising out of the earth. This beast had two horns like a lamb, but spoke like a dragon. And this beast exercised all the authority of the first beast and caused the earth and those who dwell in it to worship the first beast, whose mortal wound had been healed. And the second beast performed great signs to cause even fire from heaven to come down to earth in the presence of the people. Because of the signs it was given to perform on behalf of the first beast, it deceived those who dwell on the earth, telling them to make an image to the beast that had been wounded by the sword and yet had lived. The second beast was permitted to give breath to the image of the first beast, so that the image could speak and cause all who refused to worship it to be killed. And the second beast required all people small and great, rich and poor, free and slave, to receive a mark on their right hand or on their forehead, so that no one could buy or sell unless he had the mark—the name of the beast or the number of its name. Here is a call for wisdom: Let the one who has insight calculate the number of the beast, for it is the number of a man, and that number is 666.

Be sober-minded and alert. Your adversary the devil prowls around like a roaring lion, seeking someone to devour.

Then I saw an angel coming down from heaven with the key to the Abyss, holding in his hand a great chain. He seized the dragon, that ancient serpent who is the devil and Satan, and bound him for a thousand years. And he threw him into the Abyss, shut it, and sealed it over him, so that he could not deceive the nations until the thousand years were complete. After that, he must be released for a brief period of time. Then I saw the thrones, and those seated on them had been given authority to judge. And I saw the souls of those who had been beheaded for their testimony of Jesus and for the word of God, and those who had not worshiped the beast or its image, and had not received its mark on their foreheads or hands. And they came to life and reigned with Christ for a thousand years. The rest of the dead did not come back to life until the thousand years were complete. This is the first resurrection. Blessed and holy are those who share in the first resurrection! The second death has no power over them, but they will be priests of God and of Christ, and will reign with Him for a thousand years. When the thousand years are complete, Satan will be released from his prison, and will go out to deceive the nations in the four corners of the earth—Gog and Magog—to assemble them for battle. Their number is like the sand of the seashore. And they marched across the broad expanse of the earth and surrounded the camp of the saints and the beloved city. But fire came down from heaven and consumed them. And the devil who had deceived them was thrown into the lake of fire and sulfur, into which the beast and the false prophet had already been thrown. There they will be tormented day and night forever and ever. Then I saw a great white throne and the One seated on it. Earth and heaven fled from His presence, and no place was found for them. And I saw the dead, great and small, standing before the throne. And there were open books, and one of them was the Book of Life. And the dead were judged according to their deeds, as recorded in the books. The sea gave up its dead, and Death and Hades gave up their dead, and each one was judged according to his deeds. Then Death and Hades were thrown into the lake of fire. This is the second death—the lake of fire. And if anyone was found whose name was not written in the Book of Life, he was thrown into the lake of fire.

And the great dragon was hurled down—that ancient serpent called the devil and Satan, the deceiver of the whole world. He was hurled to the earth, and his angels with him.

For such men are false apostles, deceitful workers, masquerading as apostles of Christ. And no wonder, for Satan himself masquerades as an angel of light. It is not surprising, then, if his servants masquerade as servants of righteousness. Their end will correspond to their actions.

My little children, I am writing these things to you so that you will not sin. But if anyone does sin, we have an advocate before the Father—Jesus Christ, the Righteous One. He Himself is the atoning sacrifice for our sins, and not only for ours but also for the sins of the whole world. By this we can be sure that we have come to know Him: if we keep His commandments. If anyone says, “I know Him,” but does not keep His commandments, he is a liar, and the truth is not in him. But if anyone keeps His word, the love of God has been truly perfected in him. By this we know that we are in Him: Whoever claims to abide in Him must walk as Jesus walked. Beloved, I am not writing to you a new commandment, but an old one, which you have had from the beginning. This commandment is the message you have heard. Then again, I am also writing to you a new commandment, which is true in Him and also in you. For the darkness is fading and the true light is already shining. If anyone claims to be in the light but hates his brother, he is still in the darkness. Whoever loves his brother remains in the light, and there is no cause of stumbling in him. But whoever hates his brother is in the darkness and walks in the darkness. He does not know where he is going, because the darkness has blinded his eyes. I am writing to you, little children, because your sins have been forgiven through His name. I am writing to you, fathers, because you know Him who is from the beginning. I am writing to you, young men, because you have overcome the evil one. I have written to you, children, because you know the Father. I have written to you, fathers, because you know Him who is from the beginning. I have written to you, young men, because you are strong, and the word of God abides in you, and you have overcome the evil one. Do not love the world or anything in the world. If anyone loves the world, the love of the Father is not in him. For all that is in the world—the desires of the flesh, the desires of the eyes, and the pride of life—is not from the Father but from the world. The world is passing away, along with its desires; but whoever does the will of God remains forever. Children, it is the last hour; and just as you have heard that the antichrist is coming, so now many antichrists have appeared. This is how we know it is the last hour. They went out from us, but they did not belong to us. For if they had belonged to us, they would have remained with us. But their departure made it clear that none of them belonged to us. You, however, have an anointing from the Holy One, and all of you know the truth. I have not written to you because you lack knowledge of the truth, but because you have it, and because no lie comes from the truth. Who is the liar, if it is not the one who denies that Jesus is the Christ? This is the antichrist, who denies the Father and the Son. Whoever denies the Son does not have the Father, but whoever confesses the Son has the Father as well. As for you, let what you have heard from the beginning remain in you. If it does, you will also remain in the Son and in the Father. And this is the promise that He Himself made to us: eternal life. I have written these things to you about those who are trying to deceive you. And as for you, the anointing you received from Him remains in you, and you do not need anyone to teach you. But just as His true and genuine anointing teaches you about all things, so remain in Him as you have been taught. And now, little children, remain in Christ, so that when He appears, we may be confident and unashamed before Him at His coming. If you know that He is righteous, you also know that everyone who practices righteousness has been born of Him.

But even the archangel Michael, when he disputed with the devil over the body of Moses, did not presume to bring a slanderous charge against him, but said, “The Lord rebuke you!”

Do not neglect to show hospitality to strangers, for by so doing some people have entertained angels without knowing it.

Or do you think the Scripture says without reason that the Spirit He caused to dwell in us yearns with envy?
