Atheists May Not Believe in God, but They Still Live in His World

By Sean McDowell Published on May 6, 2017

A few years ago I hosted a student debate at my church. Three of my high school students debated three students from the local freethinking club on the historical Jesus, intelligent design and morality. The church was packed!

One of the freethinking students argued that there is no universal moral law, and hence no need for a God to ground it. As best as I can remember, he argued that morality is merely subjective and depends upon the individual or society.

But then, interestingly, during his closing speech, the same student used the opportunity of being at a church to rail against Christians for being hateful, bigoted and intolerant. In other words, he berated Christians for being immoral.

While I couldn’t say anything, since I was the moderator, I was hoping my students caught the contradiction. Do you see it? If there is no universal moral law, as he claimed in his initial speech, and morality is merely subjective, then how can he judge Christians for being immoral? In one speech he claimed that morality was subjective, but then in another speech he criticized Christians for failing to follow the objective moral laws of tolerance and love. Which is it?

Morality is Subjective, You Bigot!

The reality is that this young man held a worldview that denies objective morality. But he couldn’t consistently live it out. As Romans 2:14-16 says, he knows there is an objective moral law because it is written on his conscience, even if his worldview says contrary.

Here’s the bottom line: Even though he claims not to believe in God, he is still made by God and lives in God’s world. If God exists, then we would expect to see people who reject God, yet who live in the world God created, live out truths that reveal their knowledge that God is real. Like a light shining through the clouds, their behavior reveals that they actually inhabit the world God has made.

My Determined Behavior is Better Than Yours!

Consider another example. In his book Free Will, Sam Harris says, “Free will is an illusion.” We may think we are free, but according to Harris, our intuitions are illusory.

But this raises some troubling questions for Harris, since he has written some other books morally condemning the teachings of the Bible and the behavior of Christians. Is he being inconsistent, like the students above?

My point is simply that we know what people really believe not by what they say, but by how they really live.

After all, if determinism is true, then Christian teachings are merely the result of some natural process involving law and chance. They were not intentionally developed, but are the result of blind, material processes. So on what basis can Harris condemn them for being wrong? Since chemicals don’t have plan, purpose or any kind of teleology, in what sense are they wrong?

And why condemn the behavior of Christians or other religious folks? After all, they didn’t decide to engage in the Crusades or the Inquisition. Rather, their behavior was the result of genes, chemicals and other natural forces. They couldn’t have done any differently! In fact, according to his deterministic views, their “wrong” behavior is just as determined as his moral protest. What makes his behavior “better” than theirs?

I am certainly not defending immoral behavior done in the name of Christ. Nor am I claiming that atheists are more immoral than Christians. That’s not my point. My point is that, as Kant argued, the claim that we ought to do something implies that we can do it — morality requires free will. And since Harris denies free will, he contradicts himself when making moral condemnations.

As with the students above, he cannot consistently live out his atheist worldview. His actions reveal that he really does believe in free will, even if his worldview leads him to claim otherwise.

Living in God’s World

Other examples could be given about the existence of human value, the objectivity of beauty and more. But my point is simply that we know what people really believe not by what they say, but by how they really live. Like a ray of light shining between clouds, people reveal their true beliefs through their actions.

Many people claim not to believe in God, but in my experience, it’s only a matter of time before their lives betray them. Why? Remember, even those who don’t believe in God still live in the world God created. It’s inescapable.

    Its interesting that the materialists can’t seem to recognize when their behavior is inconsistent with what they say they believe. Or, could it be that they do recognize it, but are simply too dishonest to admit it and face up to it?

    If materialists understood their own beliefs, and lived by them, they would never object to anything as being “wrong” because in their world-view, right and wrong don’t exist.

    I can’t help but laugh at the pseudointellectuals like Harris who promote the idea we do not have free will. If that were true, who, exactly, do they think they are going to convince to change their minds on the subject? If we really do lack free will we obviously think that way because we are predisposed to do so and no amount of proselytizing on Harris’ or anyone else’s part, can change that. The logic of atheists, got to love it.

    • Gary

      Yes. And why do they object to religion? If their atheism is not the product of free will, then neither are religious beliefs.

      • GLT

        That’s why I see them them as pseudo intellectuals, their depth of critical thinking is extremely shallow. They spout rhetoric without applying any rational thought to what they are actually saying.

      The Flying Spaghetti Monster made you say that. Prove me wrong. 🙂

      Getzlaf was an absolute monster again last night, he just willed Anaheim to win. Looks like Crosby is going to play game 5 too. May have to start pulling for a Ducks / Pens final.

        “The Flying Spaghetti Monster made you say that. Prove me wrong. :)”

        If that is what you wish to believe, how can I prove you wrong? However, because you wish to believe that does not make it correct that the FSM and I had a conversation, now does it. 🙂 Funny how you would invoke a mythical deity in an attempt to ridicule the existence of another, in your mind, mythical deity. I know you’re smart enough to know that to posit the existence of a deity in opposition to another is not evidence against the existence of that other.

        Getzlaf has a history of doing that. I don’t know if you saw the 2005 World Junior Championship but he did the same thing there. What a dream team that was. Getzlaf, Perry, Crosby, Bergeron, Seabrook, Weber, Carter,…” They just rolled over the competition.

        I cannot believe they did not call goalie interference on Kesler. He did exactly what I would have done that situation, so I don’t Blame Kesler but it should be called. They keep saying they put in replays to get it right, well then, get it right.

        I’m still going to hope for an Oilers/Senators final, though it is looking bleak, as I would love to watch Bettman squirm. Though with the teams remaining (outside of the Rangers, I just don’t like that team) the final will consist of two quality teams.

    Every single person in the world declares the existence of God. “I am”.

  • AvgJoe

    This is basically the same as people who deny the existence of objective truth, but then spend a lot time trying to convince you that what they say is true.
