Revelation 1: 14-16

¹⁴ The hair on his head was white like wool, as white as snow, and his eyes were like blazing fire. ¹⁵ His feet were like bronze glowing in a furnace, and his voice was like the sound of rushing waters. ¹⁶ In his right hand he held seven stars, and coming out of his mouth was a sharp, double-edged sword. His face was like the sun shining in all its brilliance.

Revelation 1:19-20

¹⁹ “Write, therefore, what you have seen, what is now and what will take place later. ²⁰ The mystery of the seven stars that you saw in my right hand and of the seven golden lampstands is this: The seven stars are the angels of the seven churches, and the seven lampstands are the seven churches."

In these verses Jesus makes it clear what the seven lampstands and the seven angels were referring to earlier. One source I found suggested that the word angel could also be translated as messenger, so that the verse may reference human pastors or disciples. 

Revelation 2:7-10

⁷Whoever has ears, let them hear what the Spirit says to the churches. To the one who is victorious, I will give the right to eat from the tree of life, which is in the paradise of God.

⁸ “To the angel of the church in Smyrna write: These are the words of him who is the First and the Last, who died and came to life again. ⁹ I know your afflictions and your poverty—yet you are rich! I know about the slander of those who say they are Jews and are not, but are a synagogue of Satan. ¹⁰ Do not be afraid of what you are about to suffer. I tell you, the devil will put some of you in prison to test you, and you will suffer persecution for ten days. Be faithful, even to the point of death, and I will give you life as your victor’s crown.

Revelation 2: 11-13

 ^{11 "}Whoever has ears, let them hear what the Spirit says to the churches. The one who is victorious will not be hurt at all by the second death.

¹² “To the angel of the church in Pergamum write:

These are the words of him who has the sharp, double-edged sword. ¹³ I know where you live—where Satan has his throne. Yet you remain true to my name. You did not renounce your faith in me, not even in the days of Antipas, my faithful witness, who was put to death in your city—where Satan lives."

Revelation 3: 1-3

 “To the angel of the church in Sardis write:

 These are the words of him who holds the seven spirits of God and the seven stars. I know your deeds; you have a reputation of being alive, but you are dead. ² Wake up! Strengthen what remains and is about to die, for I have found your deeds unfinished in the sight of my God. ³ Remember, therefore, what you have received and heard; hold it fast, and repent. But if you do not wake up, I will come like a thief, and you will not know at what time I will come to you.

 This link at davidschrock.com gives several interpretations about what Jesus may mean by "the seven spirits of God" in this verse, referencing verses of prophecy in Isaiah 11:1-5. The writer notes that the seven qualities in Isaiah 11:2 are described as the "sevenfold spirit of God".

Revelation 3: 4-6

 In Revelation chapter three, verses four through six, Jesus continues his admonition to the Church in Sardis. He says, 

"Yet you have a few people in Sardis who have not soiled their clothes. They will walk with me, dressed in white, for they are worthy. ⁵ The one who is victorious will, like them, be dressed in white. I will never blot out the name of that person from the book of life, but will acknowledge that name before my Father and his angels. ⁶ Whoever has ears, let them hear what the Spirit says to the churches."

This passage is pretty clear cut; here Jesus acknowledges that some members of the church at Sardis are still in good standing; he uses the metaphor of wearing white clothing to signify the remaining purity of their souls. He is telling the congregation that their deeds matter and to cling to his teachings and remain repentant until the day of his second coming so that their name will remain in the book of life. 

Revelation 3: 9-10

 ⁹ I will make those who are of the synagogue of Satan, who claim to be Jews though they are not, but are liars—I will make them come and fall down at your feet and acknowledge that I have loved you. ¹⁰ Since you have kept my command to endure patiently, I will also keep you from the hour of trial that is going to come on the whole world to test the inhabitants of the earth.

I did a search on the reference to the "synagogue of Satan" in verse nine, and it appears that there is no solid knowledge about which strain of Judaism Jesus is referring to in this letter addressed to the Christian members of the church at Philadelphia. Scholars infer that it might likely be a sect Christ regarded as he did the Pharisees, which clung to man-made religious law rather than the laws of God. Other articles I looked at suggested that the 'Synagogue of Satan' may have been a sect trying to impress circumcision on Christians and pressure them to adopt and follow Mosaic law.

 

Revelation 3: 11-13

¹¹ I am coming soon. Hold on to what you have, so that no one will take your crown. ¹² The one who is victorious I will make a pillar in the temple of my God. Never again will they leave it. I will write on them the name of my God and the name of the city of my God, the new Jerusalem, which is coming down out of heaven from my God; and I will also write on them my new name. ¹³ Whoever has ears, let them hear what the Spirit says to the churches.

 

Here Jesus is encouraging his followers in the church of Philadelphia to cleave to their beliefs about Salvation and continue to repent and obey the laws of Christ so that they can keep what He implies are their already steadfast beliefs in God. 

Revelation 3: 14-18

 “To the angel of the church in Laodicea write:

These are the words of the Amen, the faithful and true witness, the ruler of God’s creation. ¹⁵ I know your deeds, that you are neither cold nor hot. I wish you were either one or the other! ¹⁶ So, because you are lukewarm—neither hot nor cold—I am about to spit you out of my mouth. ¹⁷ You say, ‘I am rich; I have acquired wealth and do not need a thing.’ But you do not realize that you are wretched, pitiful, poor, blind and naked. ¹⁸ I counsel you to buy from me gold refined in the fire, so you can become rich; and white clothes to wear, so you can cover your shameful nakedness; and salve to put on your eyes, so you can see. 

 

There are still many ruins left standing at Laodicea; this article talks about both the ruins and the "lukewarm" parishioners of Laodicea who were trying to avoid being killed by the emperor Domitian for not worshipping him as emperor, as well as the imperial cult dynasties.

Revelation 3:19-21

 These are the last few verses of Revelation chapter three, which finishes Jesus' message to the church in Laodicea:

¹⁹ Those whom I love I rebuke and discipline. So be earnest and repent. ²⁰ Here I am! I stand at the door and knock. If anyone hears my voice and opens the door, I will come in and eat with that person, and they with me.

²¹ To the one who is victorious, I will give the right to sit with me on my throne, just as I was victorious and sat down with my Father on his throne. ²² Whoever has ears, let them hear what the Spirit says to the churches.”

 

Revelation 4:7-8

"Around the throne, and on each side of the throne, are four living creatures, full of eyes in front and behind: ⁷ the first living creature like a lion, the second living creature like an ox, the third living creature with a face like a human face, and the fourth living creature like a flying eagle. ⁸ And the four living creatures, each of them with six wings, are full of eyes all around and inside. Day and night without ceasing they sing,

“Holy, holy, holy,
the Lord God the Almighty,
    who was and is and is to come.”

Revelation 4:9-11

 

^"9 And whenever the living creatures give glory and honor and thanks to the one who is seated on the throne, who lives forever and ever, ¹⁰ the twenty-four elders fall before the one who is seated on the throne and worship the one who lives forever and ever; they cast their crowns before the throne, singing,

¹¹ “You are worthy, our Lord and God,
    to receive glory and honor and power,
for you created all things,
    and by your will they existed and were created.” 

Revelation 5:1-5

 

5 Then I saw in the right hand of the one seated on the throne a scroll written on the inside and on the back, sealed with seven seals; ² and I saw a mighty angel proclaiming with a loud voice, “Who is worthy to open the scroll and break its seals?” ³ And no one in heaven or on earth or under the earth was able to open the scroll or to look into it. ⁴ And I began to weep bitterly because no one was found worthy to open the scroll or to look into it. ⁵ Then one of the elders said to me, “Do not weep. See, the Lion of the tribe of Judah, the Root of David, has conquered, so that he can open the scroll and its seven seals.”

 

Revelation 6:1-2

Then I saw the Lamb open one of the seven seals, and I heard one of the four living creatures call out, as with a voice of thunder, “Come!”  I looked, and there was a white horse! Its rider had a bow; a crown was given to him, and he came out conquering and to conquer. 

Revelation 6:9-11

 

^"9 When he opened the fifth seal, I saw under the altar the souls of those who had been slaughtered for the word of God and for the testimony they had given; ¹⁰ they cried out with a loud voice, “Sovereign Lord, holy and true, how long will it be before you judge and avenge our blood on the inhabitants of the earth?” ¹¹ They were each given a white robe and told to rest a little longer, until the number would be complete both of their fellow servants and of their brothers and sisters, who were soon to be killed as they themselves had been killed."

Revelation 6: 12-17

 

¹² When he opened the sixth seal, I looked, and there came a great earthquake; the sun became black as sackcloth, the full moon became like blood, ¹³ and the stars of the sky fell to the earth as the fig tree drops its winter fruit when shaken by a gale. ¹⁴ The sky vanished like a scroll rolling itself up, and every mountain and island was removed from its place. 

  ¹⁵ Then the kings of the earth and the magnates and the generals and the rich and the powerful, and everyone, slave and free, hid in the caves and among the rocks of the mountains, ¹⁶ calling to the mountains and rocks, “Fall on us and hide us from the face of the one seated on the throne and from the wrath of the Lamb; ¹⁷ for the great day of their wrath has come, and who is able to stand?”

Revelation 7: 9-12

⁹ After this I looked, and there was a great multitude that no one could count, from every nation, from all tribes and peoples and languages, standing before the throne and before the Lamb, robed in white, with palm branches in their hands. ¹⁰ They cried out in a loud voice, saying,

“Salvation belongs to our God who is seated on the throne, and to the Lamb!”

¹¹ And all the angels stood around the throne and around the elders and the four living creatures, and they fell on their faces before the throne and worshiped God, ¹² singing,

“Amen! Blessing and glory and wisdom
and thanksgiving and honor
and power and might
be to our God forever and ever! Amen.”

 

Revelation 7:13-17

 

¹³ Then one of the elders addressed me, saying, “Who are these, robed in white, and where have they come from?” ¹⁴ I said to him, “Sir, you are the one that knows.” Then he said to me, “These are they who have come out of the great ordeal; they have washed their robes and made them white in the blood of the Lamb.

¹⁵ For this reason they are before the throne of God,
    and worship him day and night within his temple,
    and the one who is seated on the throne will shelter them.
¹⁶ They will hunger no more, and thirst no more;
    the sun will not strike them,
    nor any scorching heat;
¹⁷ for the Lamb at the center of the throne will be their shepherd,
    and he will guide them to springs of the water of life,
and God will wipe away every tear from their eyes.”

 

Revelation 8:1-5

 

8 When the Lamb opened the seventh seal, there was silence in heaven for about half an hour. ² And I saw the seven angels who stand before God, and seven trumpets were given to them.

³ Another angel with a golden censer came and stood at the altar; he was given a great quantity of incense to offer with the prayers of all the saints on the golden altar that is before the throne. ⁴ And the smoke of the incense, with the prayers of the saints, rose before God from the hand of the angel. ⁵ Then the angel took the censer and filled it with fire from the altar and threw it on the earth; and there were peals of thunder, rumblings, flashes of lightning, and an earthquake.

Revelation 8:6-13

 

⁶ Now the seven angels who had the seven trumpets made ready to blow them.

⁷ The first angel blew his trumpet, and there came hail and fire, mixed with blood, and they were hurled to the earth; and a third of the earth was burned up, and a third of the trees were burned up, and all green grass was burned up.

⁸ The second angel blew his trumpet, and something like a great mountain, burning with fire, was thrown into the sea. ⁹ A third of the sea became blood, a third of the living creatures in the sea died, and a third of the ships were destroyed.

¹⁰ The third angel blew his trumpet, and a great star fell from heaven, blazing like a torch, and it fell on a third of the rivers and on the springs of water. ¹¹ The name of the star is Wormwood. A third of the waters became wormwood, and many died from the water, because it was made bitter.

¹² The fourth angel blew his trumpet, and a third of the sun was struck, and a third of the moon, and a third of the stars, so that a third of their light was darkened; a third of the day was kept from shining, and likewise the night.

¹³ Then I looked, and I heard an eagle crying with a loud voice as it flew in midheaven, “Woe, woe, woe to the inhabitants of the earth, at the blasts of the other trumpets that the three angels are about to blow!”
