Before the throne there was a sea of glass like unto crystal.@Revelation 4:6
William Kuipers (1884–1933)

William Kuipers, 1932. Kuipers wrote these words while pastor of the Summer Street Christian Reformed Church (CRC) in Passaic, New Jersey, and died only a few months later. Kuipers intended for the hymn to be sung to Elgar’s Pomp and Circumstance, but as that music was under copyright, The Banner, a CRC weekly magazine, held a tune writing contest. Siebolt H. Frieswyk of Whitinsville, Massachusetts, won the contest, but Vanderhoven’s tune received honorable mention, and was published with Kuipers’ words in the 1934 Psalter Hymnal.

Crystal John L. Vanderhoven, 1933 (🔊 pdf nwc).

By the sea of crystal, saints in glory stand,
Myriads in number, drawn from every land,
Robed in white apparel, washed in Jesus’ blood,
They now reign in Heaven with the Lamb of God.

Out of tribulation, death and Satan’s hand,
They have been translated at the Lord’s command.
In their hands they’re holding palms of victory;
Hark! the jubilant chorus shouts triumphantly:

Unto God Almighty, sitting on the throne,
And the Lamb, victorious, be the praise alone,
God has wrought salvation, He did wondrous things,
Who shall not extol Thee, holy King of kings?
