The Reason To Believe By: Peter Kreeft

Why should we believe in God? There are many people that argue if God exists. One person that did not believe in God was Peter Kreeft. The evidence from his research convinced him that God does exist.  In this essay I will share some of Peter Kreeft’s main points from the reading “The Reasons to Believe”.


One argument about God’s existence is the argument from design. According to Peter Kreeft, “all things have a different order that leads them to a particular goal”.  Also, the anthropic principle tells us that the universe seems to be specifically designed for people. As well, the principle of causality says whoever created something must be smarter than the object. This is gradation. Gradation means grading somethings by good to best. So, where there is design there must be a designer – God.


A second argument for God’s existence is from conscience “first cause”. Everything happens for a cause. “If no cause, no effect. If no creator, no creation; if no God, no universe.”  What existed before the universe was created? There can only two answers. It’s either the world was already created or it was not created. I believe that world was already created because matter cannot be created or destroyed, only changed. This is something that only God can do.


Saint Thomas Aquinas strongly believes that people should not disobey their conscience. Conscience is a sense or feeling of what is right or wrong.  When forming your conscience, you should seek the truth about whether God has revealed himself to us. You will find clear moral maps in the scripture and church. Conscience is different from free will.  Free will is to have your own choice without people telling you what to do.

Society is not always right. Sometimes, you should disobey society, or your instinct, if you know you are right or for concern for others.


The argument from history is Peter Kreeft’s next reason to believe in God. History shows that humans and pre humans have a storyline. God tell us our own story. “We are a living history.” But, we are designed to live life with morals, or follow a path that is good and just. We see “the hand of God” in moral affairs when we followed his laws. A “providential coincidence” is something good that happens that you are not expecting. An example of this is the Red Sea parting just at the right time for the Jews to escape from Pharaoh. Kreeft tells us that miracles (a deed done by supernatural) directly show the presence of God. Atheists believes in miracles without reasonable cause for the miracles. Frank Morrison is the one who create the book  (who move the stone). He investigate the evidence for the myth of Christ resurrection. Lewis’s trilemma is an apologetic argument traditionally used to argue for the divinity of Jesus by arguing that the only alternatives were that he was evil or deluded. The difference between personality and character is personality shows what you are outside or what you are to the world, character reveals what you are inside. Christ won our hearts by his miracle of an amazing grace. We can seek God not by arguing but by praying to him. An agnostic is a person who does not believe in God’s existence.


Pascal’s Wager is the final argument that Peter Kreeft presents. Self preservation is a behaviour that ensures the survival of an creature. Humans can act this way.

Agnosticism is a person who is uncertain about God’s existence. They are waiting for a miracle to happen that prove the existence of God.  Theism is people who believe in God existence. By “betting on God” you don’t lose anything if God does not exist. But if God does exist you gain the faith of God saving you from your sins.


I agree with St.Thomas Aquinas and believe that God does exist. The most convincing is the Argument from Design, this tell me that something cannot created by nothing. And if there’s a design there must be a designers. Why do believe in God? Why not, you’re not losing anything by believing in God.
