The seventh angel sounded, and there were great voices in Heaven, saying,
Revelation 11:15The kingdoms of this world are become the kingdoms of our Lord, and of His Christ; and He shall reign forever and ever.
Words: Isaac Watts, Hymns and Spiritual Songs 1707. The kingdoms of the world become the kingdoms of the Lord; or, the day of judgment.
Music: Hesperus Henry Baker, 1854. First published in A Hymnal for Use in the English Church, by John Grey, 1866 (🔊 pdf nwc).

Let the seventh angel sound on high,
Let shouts be heard through all the sky;
Kings of the earth, with glad accord,
Give up your kingdoms to the Lord.
Almighty God, Thy power assume,
Who wast, and art, and art to come:
Jesus, the Lamb who once was slain,
For ever live, for ever reign!
The angry nations fret and roar,
That they can slay the saints no more
On wings of vengeance flies our God,
To pay the long arrears of blood.
Now must the rising dead appear;
Now the decisive sentence hear;
Now the dear martyrs of the Lord
Receive an infinite reward.
