“In this worship of God and the Lamb by the whole creation (Revelation 5:13) the eschatological goal of God’s purpose for His creation is already anticipated. Appropriately, therefore, the living creatures, who continually express creation’s worship with this goal in view, join their own ‘Amen!’ to it when the goal is reached. (5:14).
It is worth noticing how far from anthropocentric is this vision of worship. Humanity is radically displaced from the center of things where human beings naturally tend to place themselves. At its heart and in its eschatological goal the creation is theocentric, orientated in worship towards its Creator.”
