The Gutenberg Bible, the first Bible to be printed with a movable type printing press, making it able to be mass produced and more widely available.
In this interlude in the Trumpets narrative, the angel, or Yeshua the sent one, gives John a little book, the Bible’s Book of Revelation, for him to meditate on, digest, make part of his life, and speak out. He was prevented from writing some of the revelation given him, which may remain to yet be revealed to End Time believers.
The Bible was open, meaning it was becoming available to the masses in the late 15th Century.
1 I saw another strong angel coming down out of heaven, clothed with a cloud; and the rainbow was upon his head, and his face was like the sun, and his feet like pillars of fire [Yeshua, compare with description in Rev 1; Yeshua is called “the angel of Yahweh” in the O.T.]
2 and he had in his hand a little book [the Bible/Revelation] which was open [the Gutenburg Bible was first produced on a printing press just as Constantinople was falling to the Muslims in the early 1450s, the first time the Word of God began to be widely available]. He placed his right foot on the sea and his left on the land [Yeshua is in control of both the stable and unstable portions of the world];
3 and he cried out with a loud voice, as when a lion roars [He is the Lion of the tribe of Judah, Rev 5:5]; and when he had cried out, the seven peals of thunder uttered their voices.
4 When the seven peals of thunder had spoken, I was about to write; and I heard a voice from heaven saying, “ Seal up the things which the seven peals of thunder have spoken and do not write them [there are some mysteries that aren’t explained in the book of Revelation, but perhaps will be revealed in the ‘End Times’, due to the fact that their existence has been revealed].”
5, 6 Then the angel [Yeshua the Son] whom I saw standing on the sea and on the land lifted up his right hand to heaven, and swore by Him [Yahweh the Father] who lives forever and ever, who created heaven and the things in it, and the earth and the things in it, and the sea and the things in it, that there will be delay no longer [God has “delayed” because He is not willing that any should be lost, 2 Pet 3:9],
7 but in the days of the voice of the seventh angel, when he is about to sound [the last trumpet, 1 Cor 15:52], then the mystery of God is finished [judgment and the kingdom of God will come openly to earth], as He preached to His servants the prophets [the “Day of the Lord”, discussed often in the O.T.].
8 Then the voice which I heard from heaven, I heard again speaking with me, and saying, “Go, take the book [the Bible/Revelation] which is open in the hand of the angel [Yeshua, the angel of the LORD] who stands on the sea and on the land [He is in control of both the stable and unstable portions of the world].”
9 So I went to the angel [Yeshua], telling him to give me the little book [the Bible/Revelation]. And he said to me, “ Take it and eat it; it will make your stomach bitter, but in your mouth it will be sweet as honey [when we understand its implications, we are made sick to our stomachs, but there is a sweetness in proclaiming the truth].”
10 I took the little book out of the angel’s hand and ate it [meditated on the Word of God, “digested” it, made it part of his life], and in my mouth it was sweet as honey [when he first took it in, and when he spoke it out]; and when I had eaten it, my stomach was made bitter [there is a retched feeling one gets when considering the implication of man’s sin and the judgments to come].
11 And they [God the Father and God the Son] said to me, “You must prophesy again concerning many peoples and nations and tongues and kings [thus Revelation continues].”

Kurt – In reference to those who say that the church is not mentioned after Rev chap 3 – In Rev 4:1-2 John was taken up into heaven (spiritually which must mean not physically??) There not not seem to be any where that says he came back down until he seen ALL OF Rev unfold like a DVD movie in heaven for lack of a better description.
So is he was in heaven spiritually watching this DVD it would be natural to assume that the church was not there in heaven either so it must still have remained on the earth.
When we get to Rev 22:16 we once again see the word churchES which must be a reference back to the seven churchES – Chap 22 being the last chapter in the bible also appears to be at the very end – judgment time if one looks at the verses just before and after v16.
It seems to provide evidence that the churches do actually go through the tribulation – what do you think
Rev 22:16 “I, Jesus, have sent my angel to give you this testimony for the churches. I am the Root l and the Offspring of David, and the bright Morning Star
John writes in Rev 1:10 & 11: I was in the Spirit on the Lord’s day, and I heard behind me a loud voice like the sound of a trumpet, 11 saying, “ Write in a book what you see, and send it to the seven churches: to Ephesus and to Smyrna and to Pergamum and to Thyatira and to Sardis and to Philadelphia and to Laodicea.”
John says he was “in the Spirit”. This is a vision John has, and records it in a book as he is commanded.
In John 4, it is similar; John never went to Heaven. The passage says “After these things I looked, and behold, a door standing open in heaven, and the first voice which I had heard, like the sound of a trumpet speaking with me, said, “ Come up here, and I will show you what must take place after these things.” 2 Immediately I was in the Spirit; and behold, a throne was standing in heaven, and One sitting on the throne.”
These are visions only.
The whole argument of the church not being present after Chapter 4 is tiresome. As we both know “saints (hagios)” is used interchangeably throughout the bible to indicate the Ekklesia, the “called out ones” of God, and that word appears in Revelation beyond Chapter 4.
