A            Em
Eternal God, unchanging
D                 A
Mysterious and unknown
                  Em
Your boundless love, unfailing
      D                  A
In grace and mercy shown
      F#m            D            F#m                  D
Bright seraphim in ceaseless flight around Your glorious throne
      A            Em                 D            A
They raise their voices day and night in praise to You alone

V2-

A                  Em
Lord, we are weak and frail
D            A
Helpless in the storm
                  Em
Surround us with Your angels
D                 A
Hold us in Your arms
       F#m            D              F#m            D
Our cold and ruthless enemy, his pleasure is our harm
A                   Em           D                  A
Rise up, O Lord, and he will flee before our sovereign God


V3-

A                Em                 D            A
Let every creature in the sea and every flying bird
                        Em            D           A
Let every mountain, every field and valley of the earth
       F#m            D              F#m          D
Let all the moons and all the stars in all the universe
      A            Em            D            A
Sing praises to the living God who rules them by His word
