The book of Revelation is a prophetical book; therefore it had to have been written by a Prophet.Luke 16:16–The LAW and the PROPHETS were UNTIL JOHN: since that time the kingdom of God is preached, and every man presseth into it
.Luke 7:28—For I say unto you, Among those that are born of women there is not a greater prophet than John the Baptist; but he that is least in the kingdom of God is greater than he.See, this is showing that prophets did not come into the era of the kingdom of God; the very least of us, are greater than the greatest prophet.There were no prophets, receiving the Word of God, since John the Baptist. Paul, and the other N.T. writters only wrote epistles; not prophet books. Revelation is the only prophet book in the N.T. Scriptures; therefore, it had to have been written by a prophet; of which John the Baptist was the last one
.John 1:6—There was a man sent from God, whose name was John.v7–The same came for a witness, to bear witness of the LIGHT, that all men through him might believe.v8—He was not that Light, but was sent to bear witness of that Light.Rev.1:1–The Revelation of Jesus Christ, which God gave unto him, to show unto his servants (prophets)–things which must shortly come to pass; and he sent and signified it by his angel unto his SERVANT JOHN:v2–Who bare RECORD of the word of God, and of the testimony of Jesus Christ, and of all things that he saw.
Now, bearing witness and bearing record means the same thing. So, John the Baptist is the one whom God sent to bare record, witness of Jesus, the Light.Another thing, after the resurrection, Jesus opened the understanding of all his disciples, including John, the disciple. Jesus taught these men himself.But, notice, that the John who wrote Revelation was taught by an angel. The angel of the Lord brought this Revelation to John the Baptist; for this is the way the prophets received the Word: God gave the Word to angels (whom He called gods)—then the angels delivered the Word to prophets. N.T. people do not receive the Word this way.
We are taught by the Holy Ghost. He will lead you and guide you into all truth. John the disciple was taught by Jesus; not an angel. John the Baptist was the one who was sent to prepare the way for Jesus; he is the one who bare record of Jesus. He was the last O.T. prophet
