If you ask church leaders today what is the central act of worship, most would say praise music; a few would say, Holy Communion. But in heaven it is not the praises of God’s people, or of the angels which are central, not the saints’ communion with Him or with one another, but it is the Word who is the center of all.
Revelation 21:22-23 (KJV)
22 And I saw no temple therein: for the Lord God Almighty and the Lamb are the temple of it.
23 And the city had no need of the sun, neither of the moon, to shine in it: for the glory of God did lighten it, and the Lamb is the light thereof.
