Jesus says in Revelation (NKJV):
“Because you have kept My command to persevere, I also will keep you from the hour of trial which shall come upon the whole world, to test those who dwell on the earth.” 3:10.
“He who has an ear, let him hear what the Spirit says to the churches. 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. He who has an ear, let him hear what the Spirit says to the churches. He who overcomes shall not be hurt by the second death.” 2:10-11
“He who has an ear, let him hear what the Spirit says to the churches. 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 – ‘He shall rule them with a rod of iron; they shall be dashed to pieces like the potter’s vessels’ and I will give him the morning star.” 2:26-28
“You have a few names even in Sardis who have not defiled their garments; and they shall walk with Me in white, for they are worthy. He who overcomes shall be clothed in white garments, and I will not blot out his name from the Book of Life; but I will confess his name before My Father and before His angels.” 3:4-5
“Behold, I am coming quickly! Hold fast what you have, that no one may take your crown. He who overcomes, I will make him a pillar in the temple of My God, and he shall go out no more. I will write on him the name of My God and the name of the city of My God, the New Jerusalem, which comes down out of heaven from My God. And I will write on him My new name.” 3:11-12.
“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.” 22:12-13.
