• O God of burning altar fire,
  O God of love’s consuming flame,
  Make pure the flame of our desire
  To win the lost to seek Thy Name.
• There is no coldness, Lord, in Thee,
  Oh, keep us kindled lest we bring
  To our dear Lord of Calvary,
  Dead ashes for our offering.
• Dead ashes, husk of corn for wheat
  Lord of our consecration vow,
  We gather round Thy wounded feet,
  We see the thorn about Thy brow.
• Oh, by Thy cross and passion, Lord,
  Grant us this plea, this sovereign plea,
  Save us from choosing peace for sword,
  And give us souls to give to Thee.
