Born in 1937, Peter Kreeft is a professor of philosophy and the prolific author of over eighty books on such topics as Christian philosophy, theology, and apologetics. Although a convert to Roman Catholicism, Kreeft places his central emphasis on the unity between Catholics and Protestants. A brilliant thinker, Kreeft, has a wonderful way of using logic to convey rich spiritual truths. His quotes below should give you some important food for thought.1
“One of the few things in life that cannot possibly do harm in the end is the honest pursuit of the truth.”
“In an age of hope men looked up at the night sky and saw ‘the heavens.’ In an age of hopelessness, they call it simply ‘space.’”
“God created the possibility of evil; people actualized that potentiality. The source of evil is not God’s power but mankind’s freedom. Even an all-powerful God could not have created a world in which people had genuine freedom and yet there was no potentiality for sin, because our freedom includes the possibility of sin within its own meaning.”
“The greatest Christians in history seem to say that their sufferings ended up bringing them the closest to God – so this is the best thing that could happen, not the worst.”
“On my door is a cartoon of two turtles. One says, ‘Sometimes I would like to ask why he allows poverty, famine and injustice when he could do something about it.’ The other turtle says, ‘I am afraid that God might ask me the same question.’”
“If we had absolute proof instead of clues, then you could no more deny God than you could deny the sun. If we had no evidence at all, you could never get there. God gives us just enough evidence so that those who want him can have him.”
“Sinners think they are saints, but saints know they are sinners.”
“Atheism cheapens everything it touches – look at the results of communism, the most powerful form of atheism on earth.”
“Why would the apostles lie?…. Liars always lie for selfish reasons. If they lied, what was their motive, what did they get out of it? What they got out of it was misunderstanding, rejection, persecution, torture, and martyrdom. Hardly a list of perks!”
“Other religions are stories of man’s search for God. The Bible is the story of God’s search for man.”
“Trying to fill the God-sized hole in our hearts with things other than God is like trying to fill the Grand Canyon with marbles.”
“Today, idols are not made of wood, stone, or brass. They are made of money, sex, and power.”
“The national anthem of Hell is ‘I did it my way.’”
“Conscience is thus explained only as the voice of God in the soul.”
“Our life here on Earth has as its purpose precisely to prepare for our eternal happiness. This world is a large womb. It is a ‘test’ as all opportunities are tests.”
“Christ transforms the meaning and value of suffering from something to be feared or at best endured into something redemptive [and transformative].”
“We do not do good works to get into heaven; we do good works because heaven has gotten to us.”
“Christianity is God’s marriage proposal to the soul.”
