In truth we know by experience that song has great force and vigour to move and inflame the hearts of men to invoke and praise God with a more vehement and ardent zeal.
John CalvinFor until men recognize that they owe everything to God, that they are nourished by His fatherly care, that He is the Author of their every good, that they should seek nothing beyond Him - they will never yield Him willing service. Nay, unless they establish their complete happiness in Him, they will never give themselves truly and sincerely to Him.
John Calvin
