John was caught up twice, the first in Rev.1:v.10. John made a travel in the time and in the space and was brought to this time of Apocalypse, and what he saw he did write the things of the chapters 1to3,
In the second time, John was caught up to the third heaven (Rev.4:v.1-2), and all things he did see is written in Revelation from chapter 4 to 22.
Around 60 years after JESUS ascention, our Lord was, let us say, "worried" with His people, with the Churches, not only of that time of the Churches of Asia, around year 95AD, but also of our time simultaneously, maybe much more "worried" with His Church of this time of the end, that is time of Apocalypse, because apostasy would grow exceendingly in this time (1Tim.4:v.1& 2Thes.2:v. 2-4), this is the main signal of the manifestation of the MAN of sin, the son of perdition, even him whose coming is after the working of Satan with all power and signs and lying wonders.
The things exposed above reffer to what John saw in his FIRST RAPTURE, and are written in Revelation Chapters 1-2&3 - whose things were happening in the 7 Churches of Asia around the year 95, and the same are happening in this end of time, and will happen during the Antichrist's kingdom that will be established soon, very soon.
After these things John was raptured by the second time, now from the Lord's Day, that is this seventh and last Day or seventh and last millennium, to the third heaven where was showed unto him all things as they are written in the chapters 4 to 22.
Revelation 4:v.1-2
1 - After this I - John - looked, and, behold, a door was opened in heaven: and the first voice which I heard was as it were of a trumpet talking with me; which said, Come up hither, and I will shew thee things which must be hereafter.
2 - And immediately I was in the spirit: and, behold, a throne was set in heaven, and one sat on the throne.
Everything John did write about the 7 Churches of Asia in Revelation chap.2-3, were happening in his time around the year 95, and are happening also in this end of the time, and is and will be worse than that time.
What was hapenning with the angels of the Churches in the year 95AD?
Church of Ephesus - the angel left his first love and was fallen - And the Church?
1 - Conditions of the angel of the church of Ephesus: Rev. 2:4-5 - 4 Nevertheless I have somewhat against thee, because thou hast left thy first love. 5 Remember therefore from whence thou art fallen, and repent, and do the first works; or else I will come unto thee quickly, and will remove thy candlestick out of his place, except thou repent.
Church of Pergamos - the angel was tolerant with bad things-idolatry, fornications
2 - Conditions of the angel of the church of Pergamos - Rev. 2:14-16 - 14 But I have a few things against thee, because thou hast there them that hold the doctrine of Balaam, who taught Balac to cast a stumblingblock before the children of Israel, to eat things sacrificed unto idols, and to commit fornication. 15 So hast thou also them that hold the doctrine of the Nicolaitanes, which thing I hate. 16 Repent; or else I will come unto thee quickly, and will fight against them with the sword of my mouth.
Church of Thyatira - the angel was tolerant with fornications and with the devilish Jezabel's doctines of idolatries and more fornications
3 - Conditions of the angel of the church of Thyatira - Rev.2: 20-21 - 20 Notwithstanding I have a few things against thee, because thou sufferest that woman Jezebel, which calleth herself a prophetess, to teach and to seduce my servants to commit fornication, and to eat things sacrificed unto idols. 21 And I gave her space to repent of her fornication; and she repented not.
Chuch of Sardis - the angel was spiritually dead - And the Church?
4 - Conditions of the angel of the angel of Sardis - Rev.3:1-3 - And unto the angel of the church in Sardis write; These things saith he that hath the seven Spirits of God, and the seven stars; I know thy works, that thou hast a name that thou livest, and art dead. (The dead praise not the Lord, ...(Psalms 115:v.17) 2 Be watchful, and strengthen the things which remain, that are ready to die: for I have not found thy works perfect before God. 3 Remember therefore how thou hast received and heard, and hold fast, and repent. If therefore thou shalt not watch, I will come on thee as a thief, and thou shalt not know what hour I will come upon thee.
Church of Laodiceah - the angel was wretched, miserable, poor, BLIND and naaked. And the Church?
5 - Conditions of the angel of the church of Laodiceah - Rev.3:16-17 - 16 So then because thou art lukewarm, and neither cold nor hot, I will spue thee out of my mouth. 17 Because thou sayest, I am rich, and increased with goods, and have need of nothing; and knowest not that thou art wretched, and miserable, and poor, and BLIND, and naked: (if the blind lead the blind, both shall fall into the ditch.)
Churches of Smyrna and Philadelphia
6 - About the Churches of Smyrna and Philadelphia, there was not problems with the angels of them, but whith the members and admirers of the Jews or inhabitants of Israel:
Rev. 2:v.9 - I know thy works, and tribulation, and poverty, (but thou art rich) and I know the blasphemy of them which say they are Jews, and are not, but are the synagogue of Satan. Rev. 3:9 - Behold, I will make them of the synagogue of Satan, which say they are Jews, and are not, but do lie; behold, I will make them to come and worship before thy feet, and to know that I have loved thee.
All these things above are happening in the Churches of the present time, the time of Apocalypse, where many members or almost all members are admirers of the Jews in general, and discern not them which are liars and are of the synagogue of Satan.
Brethren, notice that until this moment described in Revelation chapters 1 to 3 the apostle John had not yet been caught up into heaven, but to the Lord's Day only, the seventh and last Day or seventh and last millennium (Rev.1:v.10).
John was caught up twice and by the second time from the Lord's Day - that is the seventh and last Day or seventh and last millennium - unto heaven as is written in Revelation 4:v.1.
