Revelation 1:1-3

1 The revelation from Jesus Christ, which God gave Him to show His servants what must soon take place. He made it known by sending his angel to his servant John, ² who testifies to everything he saw—that is, the word of God and the testimony of Jesus Christ. ³ Blessed is the one who reads aloud the words of this prophecy, and blessed are those who hear it and take to heart what is written in it, because the time is near.

Revelation 1:4-6

 ⁴ John to the seven churches which are in Asia: Grace be unto you, and peace, from him which is, and which was, and which is to come; and from the seven Spirits which are before his throne;

⁵ And from Jesus Christ, who is the faithful witness, and the first begotten of the dead, and the prince of the kings of the earth. Unto him that loved us, and washed us from our sins in his own blood,

⁶ And hath made us kings and priests unto God and his Father; to him be glory and dominion for ever and ever. Amen.

Revelation 1:7-9

 ⁷ “Look, he is coming with the clouds,”
    and “every eye will see him,
even those who pierced him”;
    and all peoples on earth “will mourn because of him.”
So shall it be! Amen.

⁸ “I am the Alpha and the Omega,” says the Lord God, “who is, and who was, and who is to come, the Almighty.”

⁹ I, John, your brother and companion in the suffering and kingdom and patient endurance that are ours in Jesus, was on the island of Patmos because of the word of God and the testimony of Jesus

Revelation 1:10 -13

¹⁰ On the Lord’s Day I was in the Spirit, and I heard behind me a loud voice like a trumpet, ¹¹ which said: “Write on a scroll what you see and send it to the seven churches: to Ephesus, Smyrna, Pergamum, Thyatira, Sardis, Philadelphia and Laodicea.” ¹² I turned around to see the voice that was speaking to me. And when I turned I saw seven golden lampstands, ¹³ and among the lampstands was someone like a son of man, dressed in a robe reaching down to his feet and with a golden sash around his chest.

Revelation 1: 17-18

^{17 "}When I saw him, I fell at his feet as though dead. Then he placed his right hand on me and said: “Do not be afraid. I am the First and the Last. ¹⁸ I am the Living One; I was dead, and now look, I am alive for ever and ever! And I hold the keys of death and Hades." 

One can only imagine the feeling John must have had at this point being confronted with all this overwhelming sound and imagery, but Christ is quick to comfort him and tell him not to be afraid.

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: 1-6

“To the angel of the church in Ephesus, write:

These are the words of him who holds the seven stars in his right hand and walks among the seven golden lampstands. ² I know your deeds, your hard work and your perseverance. I know that you cannot tolerate wicked people, that you have tested those who claim to be apostles but are not, and have found them false. ³ You have persevered and have endured hardships for my name, and have not grown weary.

⁴ Yet I hold this against you: You have forsaken the love you had at first. ⁵ Consider how far you have fallen! Repent and do the things you did at first. If you do not repent, I will come to you and remove your lampstand from its place. ⁶ But you have this in your favor: You hate the practices of the Nicolaitans, which I also hate."

Revelation 2:14-17

 

¹⁴ "Nevertheless, I have a few things against you: There are some among you who hold to the teaching of Balaam, who taught Balak to entice the Israelites to sin so that they ate food sacrificed to idols and committed sexual immorality. ¹⁵ Likewise, you also have those who hold to the teaching of the Nicolaitans. ¹⁶ Repent therefore! Otherwise, I will soon come to you and will fight against them with the sword of my mouth.

¹⁷ Whoever has ears, let them hear what the Spirit says to the churches. To the one who is victorious, I will give some of the hidden manna. I will also give that person a white stone with a new name written on it, known only to the one who receives it."

Revelation 2: 18-21

 ¹⁸ “To the angel of the church in Thyatira write:

These are the words of the Son of God, whose eyes are like blazing fire and whose feet are like burnished bronze. ¹⁹ I know your deeds, your love and faith, your service and perseverance, and that you are now doing more than you did at first.

²⁰ Nevertheless, I have this against you: You tolerate the woman Jezebel, who calls herself a prophet. By her teaching she misleads my servants into sexual immorality and the eating of food sacrificed to idols. ²¹ I have given her time to repent of her immorality, but she is unwilling.

Revelation 2:26-29

²⁶ To the one who is victorious and does my will to the end, I will give authority over the nations— ²⁷ that one ‘will rule them with an iron scepter and will dash them to pieces like pottery’—just as I have received authority from my Father. ²⁸ I will also give that one the morning star. ²⁹ Whoever has ears, let them hear what the Spirit says to the churches.

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: 7-8

 Revelation chapter three, verses seven and eight, says: 

To the angel of the church in Philadelphia write:

These are the words of him who is holy and true, who holds the key of David. What he opens no one can shut, and what he shuts no one can open. I know your deeds. See, I have placed before you an open door that no one can shut. I know that you have little strength, yet you have kept my word and have not denied my name.

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 4:1-3

  

 "After this I looked, and there before me was a door standing open in heaven. And the voice I had first heard speaking to me like a trumpet said, “Come up here, and I will show you what must take place after this.” ² At once I was in the Spirit, and there before me was a throne in heaven with someone sitting on it. ³ And the one who sat there had the appearance of jasper and ruby. A rainbow that shone like an emerald encircled the throne."

 

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 5:11-14

¹¹ Then I looked, and I heard the voice of many angels surrounding the throne and the living creatures and the elders; they numbered myriads of myriads and thousands of thousands, ¹² singing with full voice,

“Worthy is the Lamb that was slaughtered
to receive power and wealth and wisdom and might
and honor and glory and blessing!”

¹³ Then I heard every creature in heaven and on earth and under the earth and in the sea, and all that is in them, singing,

“To the one seated on the throne and to the Lamb
be blessing and honor and glory and might
forever and ever!”

¹⁴ And the four living creatures said, “Amen!” And the elders fell down and worshiped.

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 6:3-4

"When he opened the second seal, I heard the second living creature call out, “Come!”  And out came another horse, bright red; its rider was permitted to take peace from the earth, so that people would slaughter one another; and he was given a great sword."

 

Revelation 6:7-8

 

⁷ When the Lamb broke the fourth seal, I heard the voice of the fourth living creature saying, “Come^[!” ⁸ I looked, and behold, an ashen horse; and the one who sat on it had the name Death, and Hades was following with him. Authority was given to them over a fourth of the earth, to kill with sword, and famine, and plague, and by the wild animals of the earth.

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.”
