In order to answer this question, let us read what the book says about itself!

Revelation 1:1 The Revelation of Jesus Christ, which God gave unto him, to shew unto  his servants things which must shortly come to pass; and he sent and signified it  by his angel unto his servant John:

It is about Jesus Christ.  It is the revealing, or unveiling of Jesus Christ.  According to many popular prophecy teachers, it is anything but a revelation of Jesus Christ.  Many people make it out to be a revelation of antichrist, or a revelation of computer technology intended to enslave humanity, or of chinese armies and explosions.  Anything but Jesus Christ!  And if they insist it is indeed a revelation of Jesus, I am sure you would be able to agree with me that their interpretation of the book makes Jesus Christ to be a very minor issue.

Rest assured, they are wrong.  It is a revelation of Jesus!  And the greatest part of the revelation of Jesus is the work of the cross to redeem mankind from his sins.  

Partial Futurism teaches that this book is a revelation of Jesus Christ and the ramifications that occurred when he was indeed revealed in His ministry.  Therefore, we see much foretold prophecy about the doom upon Jerusalem for rejecting and crucifying Jesus Christ, and about the blessings and spiritual position as New Jerusalem that the Church holds, in this book.  The perpetrators of the crucifixion were very much a big issue with Jesus Christ.  A reading of the book of Matthew will reveal the manner in which the entire narrative of the Gospel, and Jesus' entire focus of preaching and teaching changes upon Jesus' entry into Jerusalem.  He was rejected by Jerusalem, and begins to speak parable after parable concerning the judgment to fall on Jerusalem, and the kingdom being given to another nation, the church (a holy nation).  And this is actually the entire theme of Matthew chapters 21 through 25.  

The veiling of Christ is removed, and He is unveiled in this book.  That is the reason you first read a vision of John seeing Christ in the seven candlesticks, reminiscent of the seven-branched candlestick in the Tabernacle of Moses and the Temple of Solomon.  The candlestick was in the holy place in order to enlighten the room for the high priest to locate the veil behind which was the glory of God.  Naturally, then, we read of candlesticks first, and then enter into seeing the glory of God in the face of Christ as we continue reading.  

After this vision, John is shown the true and actual "day of atonement" when the true High Priest, Jesus Christ, entered into the holiest of Heaven, itself, to present His own blood, which gives rise to the reason He is also seen as a sacrificed Lamb.

Much temple imagery is used in Revelation, because Jesus is the true and only glorious God who was veiled throughout all Old Testament times behind the Temple veil in the most holy place.  

The greatest work of Christ was the cross of redemption, of course, shedding His blood for the remission of our sins.  And the events surrounding the cross included the rejection of Christ by His own bride, Jerusalem, and the acceptance of Him by those who became His New Bride, the Church.  For that reason, Revelation speaks much about the destruction of Jerusalem, who acted as the whore just as Ezekiel prophesied her to be in chapter 16.  Read this entire chapter and try to believe that the whore of Revelation is a city other than Jerusalem.

The Revelation is about Jesus and the work of the cross, and the salvation provided through it in contrast to the destruction meted out upon Jerusalem who brought about history's greatest crime in crucifying her own bridegroom, Jesus Christ.  The Bible is about the cross.  Yes, even Revelation speaks solely of events surrounding the history of the cross, including Jerusalem's destruction.

It really is a revelation of Jesus Christ in the greatest way possible -- an account of His glory revealed to the Church while His judgment was to be revealed to Jerusalem to whom He came as a groom comes to His bride, only to find her in the arms of the Beast, Rome.  This all parallels the story of the subtle beast, the serpent, turning the woman's heart away from God and submission to the first Adam.  But Christ died and got Himself another Bride, the church!  For this reason, the New Jerusalem is said to be the Bride of Christ, the Church!  

Thank God we are not going to a city, but we have already come to the heavenly Jerusalem, the Church!
But ye are come unto mount Zion, and unto the city of the living God, the heavenly Jerusalem, and to an innumerable company of angels, To the general assembly and church of the firstborn, which are written in heaven, and to God the Judge of all, and to the spirits of just men made perfect, (Heb 12:22-23)
