Some of my favorite quotations (a mixture of religious and secular):
"The pen is mightier than the sword." - Edward Bulwer-Lytton
"[We live in a culture that has] for centuries now cultivated the idea that the skeptical person is always smarter than one who believes. You can be almost as stupid as a cabbage, as long as you doubt... Today it is the skeptics who are the social conformists." - Dallas Willard
"Being a lover of freedom, when the [Nazi] revolution came, I looked to the universities to defend it, knowing that they had always boasted of their devotion to the cause of truth; but no, the universities were immediately silenced. Then I looked to the great editors of the newspapers, whose flaming editorials in days gone had proclaimed their love of freedom; but they, like the universities, were silenced in a few short weeks... Only the Church stood squarely across the path of Hitler's campaign for suppressing the truth. I never had any special interest in the Church before, but now I feel a great affection and admiration for it because the Church alone has had the courage and persistence to stand for intellectual and moral freedom. I am forced to confess that what I once despised I now praise unreservedly." - Albert Einstein
"Failure can be defined as success at things that don't matter." - Unknown
"Any intelligent fool can make things bigger, more complex, and more violent. It takes a touch of genius -- and a lot of courage -- to move in the opposite direction." - Albert Einstein
"There is no such thing as a minor lapse of integrity." - Tom Peters
"Whenever you find yourself on the side of the majority, it's time to pause and reflect." - Mark Twain
"Do all the good you can,
By all the means you can,
In all the ways you can,
In all the places you can,
At all the times you can,
To all the people you can,
As long as ever you can." - John Wesley
"Temperance may be defined as: moderation in all things healthful; total abstinence from all things harmful." - Xenophon (Greek philosopher, ca 400 BC)
[Envy is] "the consuming desire to have everyone else be as unsuccessful as you are." - Frederick Buechner
"For every thousand hacking at the leaves of evil, there is one striking at the root." - Henry David Thoreau
"The grace that does not change my life will not save my soul." - Charles Spurgeon
"Our generosity is measured not by what we give but by what we keep." - Mark Dever
"You can judge the quality of their faith from the way they behave. Discipline is an index to doctrine." - Tertullian
"A little philosophy inclineth men's minds to atheism, but depth in philosophy bringeth men's mind to religion." - Francis Bacon
"Why will God's creatures sin against his throne? Can there be such madness in beings gifted with reason's light?" - Charles Finney
