Let it stand, therefore, as an indubitable truth, which no engines can shake, that the mind of man is so entirely alienated from the righteousness of God that he cannot conceive, desire, or design any thing but what is wicked, distorted, foul, impure, and iniquitous; that his heart is so thoroughly envenomed by sin that it can breathe out nothing but corruption and rottenness; that if some men occasionally make a show of goodness, their mind is ever interwoven with hypocrisy and deceit, their soul inwardly bound with the fetters of wickedness.
John CalvinIn 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 Calvin
