I recently wrote a piece about a young man who “de-converted” from Christianity, and in it I made this assertion: “the burden of proof is on everybody!” Non-Christians attack Christianity while assuming Christians are the only ones who need to defend their beliefs. That has been the secular assumption for the last several hundred years, and by the 20^th century it became the default position of secular Western culture. And we as Christians all too often play the part, accepting the assumption of the critics. We need to understand everyone, every single person, lives by faith. All people are fundamentally religious, which is one of the reasons I dislike referring to Christians as “believers” and non-Christians as “unbelievers.” There is no such thing as an unbeliever!

The question is, who’s faith is most credible, most plausible, makes the most sense, is most logical, and has the evidence to back up its claims. When secularism became the default plausibility structure of Western civilization, a world devoid of God became the most credible and plausible worldview, and made the most sense for most people (whether God exists or not is irrelevant because as I always say, there are very few philosophical atheists). Whatever they believe, most people are practical atheists, they live as if God didn’t exist.

Western culture in its many varied forms drives practical atheism, be it in education, media, entertainment, government, etc. One example from popular culture makes the point. In most of the shows and movies we watch, all in some way deal with the fallen human condition, which is why they can be so entertaining. However, most leave out the most important piece of the puzzle: God! It’s like going to the beach in the middle of the Sahara Desert; uh, there’s something missing. I can’t watch a TV show or movie where God is ignored without shouting, you’re missing the God part!!! They want me to believe human nature as we find it, as it’s being dramatized on screen, just is, no explanation required. I’m to believe, and assume, no higher answer exists to the continual conundrums that make up the human drama? Mere matter cannot explain it. As Blaise Pascal put it in his Pensées:

What kind of freak is man? What a novelty he is, how absurd he is, how chaotic and what a mass of contradictions, and yet what a prodigy! He is judge of all things, yet a feeble worm. He is repository of truth, and yet sinks into such doubt and error. He is the glory and the scum of the universe!

 

Man’s greatness and wretchedness are so evident that the true religion must necessarily teach us that there is in man some great principle of greatness and some great principle of wretchedness.

As Christians we believe man became a freak, and displays such greatness and wretchedness, because he rebelled against his Creator (Genesis 3). No other religion or worldview or philosophy can explain why human beings are the way they are, why we are the way we are. Most don’t even try. That man is “the glory and the scum of the universe” just is. Deal with it. No, I won’t. I want to know not just that we are the way we are, but why. What Paul describes in Romans 7 captures it perfectly: why do I do what I don’t want to do, and don’t do what I want? I know how Paul feels:

What a wretched man I am! Who will rescue me from this body of death?

He gives us the answer:

Thanks be to God, who delivers me through Jesus Christ our Lord!

We might call this the apologetic from human nature. I am more confident Christianity is true because human nature is what it is, exactly the way we’ve known it for thousands of years. 

As I wonder sometimes if my Christian faith is justified, if it’s true, and not a colossal multi-thousand-year scam, I always realize if it isn’t, some other alternative must be, has to be. Unlike agnostics and practical atheists, I can’t delude myself into thinking there is no non-religious sphere of existence. Some neutral place where faith is not required. So, doggone it, I need to know why man is such glory and scum, and how he get that way! Lucky dirt cannot explain Hamlet, for example, so please explain to me what can.

The beauty of the consideration of the alternative, is that in addition to being one of the most powerful strategies in Christian apologetics, it is essential for our own personal trust that Christianity is true and real and worth living and dying for. It forces us, and others, to defend the alternatives to Christianity, whatever the issue might be. We don’t just decide not to believe in Christian position X, and then believe in nothing. When we reject X, we must believe in Y, or A, B, C, D, or any other letter of the alphabet. And in case you weren’t aware, there are no in between letters in the alphabet.

It’s rather simple, really, and doesn’t require a theology degree, or masters in apologetics. If someone says they don’t believe in Christian letter R anymore (or Christianity), then we simply ask what they do believe. Then we ask, why do you believe that’s true? Then we wait. We’ll find most people have no idea why they believe what they believe, or that they even believe anything at all! They, like most every secular person, think belief is for religious folks, and since they’re not religious they’ll wonder, why you’re asking them what they believe.

For us, it works the same way. Doubt is a normal part of existence for finite creatures, and those who don’t doubt are not normal. Have you ever met someone who is six trillion on the certitude scale? It’s annoying. For instance, I might wonder if “nature” really is created by God, so I consider the alternatives. Atheistic materialism? Pantheism? Can you think of another alternative? Genesis 1 is far more plausible, especially as we continue to learn about the infinite complexity of creation. Another example is the Bible. Is it God’s inerrant, sufficient, authoritative Word to mankind? I wrote a book called Uninvented to argue that the only alternative, that it is made up, is not the least bit plausible. No matter what the topic is, the alternative to Christianity is not the least bit plausible. Ex-Atheist C.S. Lewis got it right:

I believe in Christianity like I believe the sun has risen not because I see it, but because by it I see everything else.
