“When He opened the fifth seal, I saw under the altar the souls of those who had been slain for the word of God and for the testimony which they held. And they cried with a loud voice, saying, ‘How long, O Lord, holy and true, until You judge and avenge our blood on those who dwell on the earth?’ And a white robe was given to each of them; and it was said to them that they should rest a little while longer, until both the number of their fellow servants and their brethren, who would be killed as they were, was completed. I looked when He opened the sixth seal, and behold, there was a great earthquake; and the sun became black as sackcloth of hair, and the moon became like blood. And the stars of heaven fell to the earth, as a fig tree drops its late figs when it is shaken by a mighty wind.” Revelation 6:9-13.
“And I saw in the right hand of Him who sat on the throne a scroll written inside and on the back, sealed with seven seals. Then I saw a strong angel proclaiming with a loud voice, ‘Who is worthy to open the scroll and to loose its seals?’ And no one in heaven or on the earth or under the earth was able to open the scroll, or to look at it. So I wept much, because no one was found worthy to open and read the scroll, or to look at it.” Revelation 5:1-4.
“Before the throne there was a sea of glass, like crystal. And in the midst of the throne, and around the throne, were four living creatures full of eyes in front and in back. The first living creature was like a lion, the second living creature like a calf, the third living creature had a face like a man, and the fourth living creature was like a flying eagle. “And the four living creatures, each having six wings, were full of eyes around and within. And they do not rest day or night, saying: ‘Holy, holy, holy, Lord God Almighty, Who was and is and is to come!’” Revelation 4:6-8.
“And to the angel of the church in Sardis write, ‘These things says He who has the seven Spirits of God and the seven stars: ‘I know your works, that you have a name that you are alive, but you are dead. Be watchful, and strengthen the things which remain, that are ready to die, for I have not found your works perfect [finished or complete] before God. Remember therefore how you have received and heard; hold fast and repent. Therefore if you will not watch, I will come upon you as a thief, and you will not know what hour I will come upon you.’” Revelation 3:1-3.
“Jude, a servant of Jesus Christ, and brother of James, to those who are called, sanctified by God the Father, and preserved in Jesus Christ: Mercy, peace, and love be multiplied to you. Beloved, while I was very diligent to write to you concerning our common salvation, I found it necessary to write to you exhorting you to contend earnestly for the faith which was once for all delivered to the saints. For certain men have crept in unnoticed, who long ago were marked out for this condemnation, ungodly men, who turn the grace of our God into licentiousness and deny the only Lord God and our Lord Jesus Christ.” Jude 1-4.
“But I want to remind you, though you once knew this, that the Lord, having saved the people out of the land of Egypt, afterward destroyed those who did not believe. And the angels [fallen angels, the, “sons of God” who may have had sex with women in Genesis 6: 1-4] who did not keep their proper domain, but left their own habitation, He has reserved in everlasting chains under darkness for the judgment of the great day; as Sodom and Gomorrah, and the cities around them in a similar manner to these, having given themselves over to sexual immorality and gone after strange flesh, are set forth as an example, suffering the vengeance of eternal fire.” Jude 5-7.
