Apologetics Apologetics comes from the Greek word apologia, which means a defense, as in a court of law. Christian apologetics involves making a case for the truth of the Christian faith.

Relativism Relativism is the view that something is relative rather than absolute. That is to say, the thing in question (a truth, a moral value, a property) is the case only in relation to something else. For example, being rich is relative. Relative to most Americans, you’re probably not rich. But relative to the people of the Sudan, you are fabulously rich! By contrast, it is not just relatively true that the Cubs did not win the 2009 World Series. It is absolutely true that they did not win. Many people today think that moral principles and

When you’re going through hard times and God seems distant, apologetics can help you to remember that our faith is not based on emotions, but on the truth, and therefore you must hold on to it.

The Apostle to the Skeptics C. S. Lewis (1898–1963) rejected Christianity as a teenager for both personal and intellectual reasons. However, as an English professor at Oxford in his twenties and early thirties, Lewis was exposed to writers and friends who offered convincing reasons first for theism and eventually for Christianity. Lewis became a Christian and began to use his intellectual and literary talents to articulate and defend a Christian view of the world. He became one of the most influential Christian apologists of his generation. His books have sold more than one hundred million ...more

Objective versus Subjective Something is objective if it’s real or true independent of anyone’s opinion about it. “Water is H2O” is an objective fact. Something is subjective if it’s just a matter of personal opinion. “Vanilla tastes better than chocolate” is subjective. You can keep these terms straight by remembering that “objective” is like an object that is really there, whereas “subjective” is like a subject or a person on whose opinion something depends.

Meaning has to do with significance, why something matters. Value has to do with good and evil, right and wrong. Purpose has to do with a goal, a reason for something.

My claim is that if there is no God, then meaning, value, and purpose are ultimately human illusions. They’re just in our heads. If atheism is true, then life is really objectively meaningless, valueless, and purposeless, despite our subjective beliefs to the contrary.

In a world without God, who’s to say whose values are right and whose are wrong? There can be no objective right and wrong, only our culturally and personally relative, subjective judgments. Think of what that means! It means it’s impossible

to condemn war, oppression, or crime as evil. Nor can you praise generosity, self-sacrifice, and love as good. To kill someone or to love someone is morally equivalent. For in a universe without God, good and evil do not exist—there is only the bare, valueless fact of existence, and there is no one to say you are right and I am wrong.

Without God the universe is the result of a cosmic accident, a chance explosion. There is no reason for which it exists. As for man, he’s a freak of nature—a blind product of matter plus time plus chance. If God does not exist, then you are just

I hope you begin to understand the gravity of the alternatives before us. For if God exists, then there is hope for man. But if God does not exist, then all we are left with is despair. As one writer has aptly put it, “If God is dead, then man is dead too.”

OZYMANDIAS Percy Bysshe Shelley I met a traveller from an antique land Who said: Two vast and trunkless legs of stone Stand in the desert. Near them on the sand Half sunk, a shatter’d visage lies, whose frown And wrinkled lip and sneer of cold command Tell that its sculptor well those passions read Which yet survive, stamp’d on these lifeless things, The hand that mock’d them and the heart that fed. And on the pedestal these words appear: “My name is Ozymandias, king of kings: “Look on my works, ye Mighty, and despair!” Nothing beside remains. Round the decay Of that colossal wreck, boundless ...more

Now this is totally inconsistent. It is inconsistent to say life is objectively absurd and then to say you may create meaning for your life.

The point is this: If God does not exist, then life is objectively meaningless; but man cannot live consistently and happily knowing that life is meaningless; so in order to be happy he pretends life has meaning. But this is, of course, entirely inconsistent—for without God, man and the universe are without any real significance.

The point is that if there is no God, then objective right and wrong do not exist. As Dostoyevsky said, “All things are permitted.” But man cannot live this way. So he makes a leap of faith and affirms values anyway. And when he does so, he reveals the inadequacy of a world without God.

Biblical Christianity thus challenges the worldview of modern man. For according to the Christian worldview, God does exist, and life does not end at the grave. Biblical Christianity therefore provides the two conditions necessary for a meaningful, valuable, and purposeful life: God and immortality.

If God does not exist, then life is futile. If God does exist, then life is meaningful. Only the second of these two alternatives enables us to live happily and consistently. Therefore, it makes a huge difference whether God exists.

Fallacy A fallacy is an error in reasoning. Fallacies can be either formal or informal. A formal fallacy involves breaking the rules of logic. An informal fallacy involves an argumentative tactic that is illicit, such as reasoning in a circle. The “taxicab fallacy” would be an informal fallacy.

Cosmology Cosmology is the study of the large-scale structure and development of the universe. The Greek word kosmos means “orderly arrangement” or “world.” Pythagoras may have been the first person to use this word to refer to the universe.
