The Apocalypse, the Book of Revelation is the last testimony from the unique time of the Christ: The time when firstly angels, then John the Baptist, and the Father through signs and miracles, and the Holy Spirit by descending as a dove, and Jesus himself, all testified for those around about Jesus being the Christ who is the Son of the Father. Then there followed another period, times of Acts, when the apostles also testified, having heard Jesus, seen what the Father gave him to do, and heard the testimony of John the Baptist about Jesus being the lamb of God and light of the world. This time of apostles testifying was accompanied by the Holy Spirit testifying too, plus the miracles done by the apostles showed the Father testifying through them because they did these miracles in Jesus’ name. So Revelation capped it all off, ending this unique period of special testimonies about Jesus being Christ and Lord, the Son of God. It was all written in scripture documents, most of which have survived to this day. So we have these as testimony. Yet we also have living people who testify still of experiences they received in Jesus’ name. There are miracles done, which show the Father still supporting the testimony. The Holy Spirit still is working and still testifies of Jesus. Jesus himself still visits some, albeit few, and he testifies and they testify to this. So there are all these testimonies all backing up Jesus and confirming he is the light of the world sent by the Father. There is plenty to corroborate what the Book of Revelation says.
