I discovered this text while looking for a theologically grounded hymn for a missions conference. It is a wonderful reminder of the promise that the glory of God and knowledge of Him will cover the earth as the waters cover the sea. Note that the recorded version of the song begins with a Shofar (ram’s horn). The Israelites used this instrument in war, in official ceremonies and sacrificial observances.
 
TEXT:
Mighty Lord, extend Your kingdom
Be the truth with triumph crowned
Let the lands that sit in darkness
Hear the glorious Gospel sound
From our borders, from our borders
To the world’s remotest bound
 
By Your arm, eternal Father,
Scatter far the shades of night
Let the great Immanuel’s kingdom
Open like the morning light
Let all barriers, let all barriers
Yield before Your heavenly might
 
Come in all Your Spirit’s power
Come, your reign on earth restore
In Your strength ride forth and conquer,
Still advancing more and more
Till all people, Till all people
Shall Your holy Name adore
