“Anger and intolerance are the twin enemies of correct understanding.”

“Declare your jihad on thirteen enemies you cannot see -egoism, arrogance, conceit, selfishness, greed, lust, intolerance, anger, lying, cheating, gossiping and slandering. If you can master and destroy them, then you will be read to fight the enemy you can see.”

“Jesus is gentle, but He is not weak. He loves the sinner but is absolutely intolerant of sin. He is not a negotiator. He is Lord. It is this bristling truth that invites intolerance toward Christians. Jesus did not say, "Do your own thing. . .all roads lead to God." That would have made Jesus "politically correct," but Jesus is not politically correct. He is Lord.”

“Tolerance is an attitude of reasoned patience toward evil … a forbearance that restrains us from showing anger or inflicting punishment. Tolerance applies only to persons … never to truth. Tolerance applies to the erring, intolerance to the error … Architects are as intolerant about sand as foundations for skyscrapers as doctors are intolerant about germs in the laboratory. Tolerance does not apply to truth or principles. About these things we must be intolerant, and for this kind of intolerance, so much needed to rouse us from sentimental gush, I make a plea. Intolerance of this kind is the foundation of all stability.”

“If you think of this world as a place simply intended for our happiness, you find it quite intolerable: think of it as a place for training and correction and it's not so bad.”

“My mother said I must always be intolerant of ignorance but understanding of illiteracy.”
