CCC 1720 The New Testament uses several expressions to characterize the beatitude to which God calls man:
– the coming of the Kingdom of God;1 – the vision of God: “Blessed are the pure in heart, for they shall see God”2
– entering into the joy of the Lord;3
– entering into God’s rest:4
There we shall rest and see, we shall see and love, we shall love and praise. Behold what will be at the end without end. For what other end do we have, if not to reach the kingdom which has no end?5
