Abstract
God's Covenant with men contitutes the essence of Revelation. The first text to give account of a Covenant is the narration of Creation and the last one appears in the Gospels, when Jesus announces the New Covenant through his blood. Nevertheless, there are not two covenants, an Old one and a New one. In the Bible, the different narrations of covenants are a renewal of the unique Covenant. It's man who is summoned to change his attitude in order to answer, always in a more profound way, to God's call.
