Those who promote and teach false theories and wrong doctrines, will be held accountable at their Judgment.
Using Revelation 4:1 as a proof of a general rapture, is plainly wrong and destroys the whole 'rapture; belief.
Apostle John was on Patmos the entire time he was shown his vision of supernatural scenes for each chapter and verse of Revelation.
John specifically indicated when he was immersed in his vision and seeing and hearing a supernatural scene. He repeatedly wrote specific phrases such as “I looked” and “I heard” (and their variations) to indicate he was immersed in his vision and seeing and hearing specific supernatural scenes.
Those specific indications were written beginning in the first supernatural scene. The first supernatural scene began in Rev 1:10 (ESV): I was in the Spirit on the Lord's day, and
I heard behind me a loud voice like a trumpet
John could only initially hear the audio of the first supernatural scene, and he specifically indicated that with, “I heard.”
In Rev 1:12, John saw into his supernatural scene and specifically indicated that with “I saw.” Rev 1:12 (ESV): Then I turned
to see the voice that was speaking to me, and on turning
I saw seven golden lampstands,
Throughout Rev, you will repeatedly find those specific phrases and variations thereto. The use of those phrases specifically indicated he was seeing and/or hearing a supernatural scene in the continuation of his vision.
Rev 4:1-2 (ESV): After this
I looked, and behold, a door standing open in heaven! And the first voice, which
I had 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 behold, a throne stood in heaven, with one seated on the throne.
In Rev 4:1, John used “I looked, and behold” which prove he was seeing the first supernatural scene for Rev 4:1.
In Rev 4:1, John also said, “I had heard” in relation to the same voice he heard in Rev 1:10 (ESV): …
I heard behind me a loud voice like a trumpet …
In Rev 4:2, John used “and behold” to specifically indicate the supernatural scene was continuing with a vision into Heaven.
John was shown all of Rev by a vision of supernatural scenes for each chapter and verse. John generously indicated when he was immersed in his vision of supernatural scenes by the use phrases “I heard” and “I looked” and their variations.
In Rev 22:8, John acknowledges he was shown all of Rev by one angel, who was clearly responsible for presenting every element of every supernatural scene. Rev 22:8 (ESV): I, John, am the one who
heard and saw these things. And
when I heard and saw them, I fell down to worship at the feet of
the angel who showed them to me,
Rev 4:1 remains unfulfilled. It therefore will be the pre-Trib rapture of the Church, in complete alignment with Rev 3:10 and the supporting verses: 1 Th 1:10, 1 Th 4:16-17, 1 Cor 15:52, John 14:3 and Acts 1:11.
