This paper aims to investigate the hermeneutic consequences of the relationship between Apocalypse of John and Old Testament. The author of Patmos, possibly aiming to move his listeners to perseverance on witness of Jesus Christ, not only wrote an apocalypse - which is true - but also drew on a wide range of Old Testament texts, not to support himself by arguments, but to highlight unprecedented facets of the reality. Indeed, if his time is an epoch of tribulation, even before the faithful persons raise their prayers to God, he has already heard them and, in his eternal saving plan, has provided them a complete salvation. The old promises are fulfilled, and the lost paradise is again opened to redeemed humanity. Therefore, we do not have in hand a text that aims to instill fear, but to ignite hope, since history is definitely oriented towards an eschatological completeness in which the whole world created, sanctified, will be a great object of worship to the God who wipes away all the tears.
