Im not sure what version you are reading, but I find all sorts of comforting words from Jesus in the book:
I, John, both your brother and companion in the tribulation and kingdom and patience of Jesus Christ, (1:9)I could go on and on. The point being that Revelation is a book of comfort. God is in complete control and His children, in spite of temporal trials, will be vindicated and rewarded in the end, while the unrighteous will suffer both temporal punishment and eternal torment. As I said, these words were very appropriate for first century believers suffering at the hands of the Romans and apostate Jews.and you have persevered and have patience, and have labored for My name's sake and have not become weary. (2:3)
To him who overcomes I will give to eat from the tree of life, which is in the midst of the Paradise of God. (2:7)
Do not fear any of those things which you are about to suffer. Indeed, the devil is about to throw some of you into prison, that you may be tested, and you will have tribulation ten days. Be faithful until death, and I will give you the crown of life. (2:10)
To him who overcomes I will give some of the hidden manna to eat. And I will give him a white stone, and on the stone a new name written which no one knows except him who receives it." ' (2:17)
And he who overcomes, and keeps My works until the end, to him I will give power over the nations(2:26)
9 As many as I love, I rebuke and chasten. Therefore be zealous and repent. Behold, I stand at the door and knock. If anyone hears My voice and opens the door, I will come in to him and dine with him, and he with Me. To him who overcomes I will grant to sit with Me on My throne, as I also overcame and sat down with My Father on His throne. (3:19-21)
"And behold, I am coming quickly, and My reward is with Me, to give to every one according to his work. I am the Alpha and the Omega, the Beginning and the End, the First and the Last." Blessed are those who do His commandments, that they may have the right to the tree of life, and may enter through the gates into the city. But outside are dogs and sorcerers and sexually immoral and murderers and idolaters, and whoever loves and practices a lie. (22:12-15)
J. Stuart Russell in his book The Parousia, writes: It could not but be well known to the Jews that the great hope and faith of the Christians was the speedy coming of the Son. St James, the brother of our Lord, publicly testified in the temple that the Son of man was about to come in the clouds of heaven, It seems highly probable that the Jews, in their defiant and desperate blasphemy, when they saw the white mass hurtling through the air, raised the ribald cry, The Son is coming, in mockery of the Christian hope of the Parousia, to which they might trace a ludicrous resemblance in the strange appearance of the missile.
