Revelation 5:13

Every creature; the song of adoration that began with the living creatures and elders, and was then taken up by the angels, now spreads itself through the whole created universe; and as the echo of it comes back to the throne of God, the living creatures say, Amen, and the elders fall down and worship. In paying divine honors to Christ, Christians on earth imitate saints and angels in heaven, and prepare to mingle in their society, join in their employments, and partake of their joys for ever.
