Isn’t Believing in God Just Wishful Thinking?

The short answer: Wanting something to be true doesn’t make it false, any more than wanting it makes it true. The real question is whether there are good reasons to believe, and there are. And the God of the Bible is not the God anyone would invent just to feel better.

The argument goes like this. Life is frightening. People die. The universe is huge and doesn’t seem to care. So humans invented a big Father in the sky to make themselves feel safe, the way a small child clings to a teddy bear in the dark. Believing in God, on this view, is just a comfort blanket for people who can’t face reality.

It sounds clever. But look at it closely and it has some serious holes.

Wanting doesn’t decide anything

First, the argument proves too much. Yes, some people might believe in God because they want to. But some people might disbelieve in God because they want to, because a world without God means nobody to answer to and nobody telling them how to live. If wanting God means God isn’t real, then wanting there to be no God would mean there is one. That’s obviously silly. Motives don’t settle whether something is true. Imagine a man lost in the desert who is desperate for water. His thirst doesn’t prove there’s no oasis over the next dune. You still have to go and look.

So the honest question isn’t “Do people want God?” It’s “Is there good evidence that God is real?” And that question has real answers: a universe that had a beginning, laws of nature finely tuned for life, a sense of right and wrong that seems to bind everyone, and, most of all, a man called Jesus who lived in a real place and time and who rose from the dead. Christianity has never asked people to believe in something “done in a corner” (Acts 26:26). Peter put it bluntly: “we did not follow cleverly devised fables” (2 Peter 1:16). He and the other apostles “were eyewitnesses of His majesty.”

Some desires point to something real

Second, think about what our desires usually tell us. We get hungry, and there is such a thing as food. We get thirsty, and there’s water. We get lonely, and there are friends. Desires generally fit something real. So what about the deep longing many people feel for something more, something nothing in this world quite satisfies? The Bible says God “has also set eternity in the hearts of men” (Ecclesiastes 3:11). It’s at least as likely that this longing is a clue as that it’s a trick.

Not the God you’d invent

Third, and this is the big one, the God of the Bible is not a comfortable invention. If people were making up a God just to feel better, they would make one who approves of everything they already do. That isn’t what we find.

The God of the Bible is holy. He tells us we’re sinners who need rescuing, which nobody enjoys hearing. Jesus said, “If anyone wants to come after Me, he must deny himself and take up his cross daily and follow Me” (Luke 9:23). That isn’t the kind of thing you’d say to win a popularity contest. Christianity teaches that there will be a judgment, that we must forgive people who’ve hurt us, love our enemies, give away our money and tell the truth when it costs us. Plenty of people have found faith hard, not cosy.

And Christianity stakes everything on something that either happened or didn’t. Paul wrote, “if Christ has not been raised, our preaching is worthless, and so is your faith” (1 Corinthians 15:14). A wish-fulfilment religion wouldn’t make itself so easy to disprove. Paul was practically inviting people to check.

What to do with this

None of this means a Christian never believes for bad reasons. Some people do believe just because it’s comforting, or because their family does. That’s why it’s worth asking for yourself whether it’s true. But the “wishful thinking” argument doesn’t get anyone off the hook. It’s a way of explaining away belief without ever looking at the evidence.

Christianity is comforting, in the end. But it’s comforting the way a rescue is comforting, not the way a daydream is. A daydream makes you feel better and changes nothing. A rescue is good news because it’s real.

Think about it: Is there anything about Christianity you’d honestly rather weren’t true? What does that tell you about whether it’s just wishful thinking?

Go deeper: The Key Teachings of C. S. Lewis — Lewis noticed a longing in himself that nothing in the world could satisfy, and argued that, just as hunger points to food, a desire nothing on earth can meet points to something beyond it. Start with chapter 3, “The Longing Called Joy”.
