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 CalvinWithout knowledge of self there is no knowledge of God Our wisdom, in so far as it ought to be deemed true and solid Wisdom, consists almost entirely of two parts: the knowledge of God and of ourselves. But as these are connected together by many ties, it is not easy to determine which of the two precedes and gives birth to the other.
John CalvinThe Lord commands us to do good unto all men without exception, though the majority are very undeserving when judged according to their own merits. But scripture here helps us out with an excellent argument when it teaches us that we must not think of man's real value, but only of his creation in the image of God to which we owe all possible honor and love.
John CalvinLet us be peaceable as near as we can: let us relent of our own right: let us not strive for these worldly goods, honour and reputation: let us bear all wrongs and outrages, rather than be moved to any debate through our own fault. But in the meanwhile, let us fight for God's truth with tooth and nail.
John Calvin
