Then God Triune sent down His Holy Spirit. He filled and keeps on filling His Church, empowering her fully to execute the Great Commission given to her. Acts 2:1-8,17-21,38-39,47.
At the end of the World, when Heaven and Earth are renewed, the Lord God Almighty and the Lamb shall be the Temple of God's City. The latter has no need of the sun, for the glory of God and the Lamb is its light. And man brings the glory and honour of the nations into it.
The nations shall then see. God Triune's name shall be on their foreheads, and they shall reign for ever and ever. Jesus shall be the bright morning star, and the Spirit shall speak – while God Triune maintains His book of life. Revelation 21:1 & 21:22-26 & 22:4-5 & 22:16-21.
