Zeal is that pure and heavenly flame,  
  The fire of love supplies ;  
  While that which often bears the name,  
  Is self in a disguise. True zeal is merciful and mild,  
  Can pity and forbear ;  
  The false is headstrong, fierce and wild,  
  And breathes revenge and war.
Hymn 70 : True and False Zeal - Olney Hymns (1779)
