There is a strange thing that can happen when you start taking your faith seriously. You read more. You underline things. You start listening to sermons differently. You discover books you had never heard of. You learn words like sanctification and justification. You find commentaries, podcasts, Bible studies, and probably several people on YouTube who are very confident that everyone except them has interpreted something incorrectly.
The more you learn, the more questions you discover. Then one night you close your Bible and a much more uncomfortable question appears. Do I actually have faith, or am I just getting really good at Christianity?
Maybe you know how to explain what you believe. You know what Christians believe about Jesus. You understand more about the Bible than you did six months ago. You can recognize bad theology you would have completely missed before.
But then you look inward. And suddenly you aren’t nearly as confident. What if all of this is staying in my head? What if I’m learning about God without actually knowing Him? What if the doubts I still have mean that I don’t really believe any of this?
I’ve noticed something after years of conversations about faith.
Sometimes the people most worried about whether their faith is real are looking for something faith was never supposed to provide. Perfect certainty.
They think real faith should eventually reach a point where all the questions disappear. But the Bible gives us a much more interesting picture.
Peter Didn’t Understand Everything Either
There is a moment in John 6 that I think speaks directly to this question. Jesus has been teaching. And His teaching is difficult. Not difficult in the sense that everyone needed another cup of coffee before the sermon started. Difficult enough that people who had been following Him began questioning whether they wanted to continue.
John tells us:
“When many of his disciples heard it, they said, ‘This is a hard saying; who can listen to it?’” (John 6:60 ESV)
A few verses later, something heartbreaking happens. Many of them leave. They had heard Jesus teach. They had watched what He was doing. Some of them had probably eaten the bread when Jesus fed the crowd earlier in the chapter.
But now following Him had become harder. So Jesus turned toward the Twelve.
“Do you want to go away as well?”
I wonder what I would have said. I would like to imagine myself giving some brilliant theological answer. Peter doesn’t.
Instead, he says:
“Lord, to whom shall we go? You have the words of eternal life, and we have believed, and have come to know, that you are the Holy One of God.” (John 6:68-69 ESV)
I love Peter’s answer because he does not say, “Jesus, don’t worry. We completely understand everything You just taught.” He doesn’t. He says, in essence, I know enough about You to know where I’m staying.
Many of the other disciples were struggling with what Jesus had said. Peter was standing in the same room listening to the same teaching. The difference wasn’t that Peter had figured everything out. The difference was where Peter had decided to place his trust.
That is much closer to biblical faith than the certainty many of us are trying to manufacture.
Knowledge Is Not the Enemy of Faith
I don’t think you should be worried that you’re spending too much time learning about Christianity simply because you’re learning a lot. Study. Read your Bible. Ask questions. Learn theology. Understand why Christians believe what they believe.
Faith is not strengthened by ignorance.
You cannot grow in your trust of someone while intentionally refusing to know anything about them. Paul writes in Romans 10:17 that “faith comes from hearing, and hearing through the word of Christ.”
Truth matters. What you believe about Jesus matters. The problem isn’t knowledge. The problem comes when knowledge becomes the destination instead of the road that leads us toward Jesus.
You can study a map for hours. You can memorize every highway number. You can calculate the mileage, study the terrain, and know exactly where every turn should happen. But eventually, if you want to travel somewhere, you have to put the car in drive.
Knowledge can show you the road. Faith begins putting your life on it.
There Is a Difference Between Knowing About Jesus and Trusting Jesus
James gives us an uncomfortable reminder when he says that even demons believe that God is one. In other words, possessing correct information about God is not, by itself, saving faith. The demons are not atheists. Their theology contains some accurate information. Their problem is not that they need another Bible study. They do not love God, submit to Him, or trust Him.
That distinction matters.
But I would be careful about turning that verse into another reason to panic and start examining every thought you’ve ever had. The better question isn’t: Do I know enough? And it isn’t: Do I feel certain enough?
Maybe the better question is: What am I doing with what I know about Jesus? Peter knew something about Jesus. And because of what he knew, when everyone else started walking away, Peter stayed.
“Lord, to whom shall we go?” That’s faith. Not perfect understanding. Trust.
Doubt Doesn’t Automatically Mean Your Faith Is Fake
This is especially important if you’re new to following Jesus. You may have assumed that becoming a Christian would make everything clearer. Some things probably did become clearer. Others may have become much more complicated.
Now you’re asking questions you never bothered asking before. What does this passage mean? How do I know the Bible is trustworthy? Why does God allow suffering? Why didn’t He answer this prayer? Why do Christians disagree about this? Why don’t I feel closer to God today than I did yesterday?
Questions can feel frightening when you believe faith is supposed to eliminate them. But questions can also be evidence that you are actually engaging with what you believe.
I’ve written before about a season when I could honestly say, “I still believe in God. I just don’t understand what He’s doing.” Those are not the same sentence.
You can trust God while struggling to understand Him. John the Baptist did. Peter did. Thomas did. You probably will too.
Faith isn’t measured by how rarely you have questions. Sometimes faith is revealed by where you take them.
If you’re wrestling with that right now, I wrote more about it in I Still Believe in God. I Just Don’t Understand What He’s Doing.
Stop Checking Your Spiritual Pulse Every Five Minutes
There is another danger hidden inside this question. We can become so concerned about whether our faith is genuine that we spend more time examining our faith than looking at Jesus.
How strong is my faith today? Did I really mean that prayer? Why didn’t I feel anything when I read that passage? Did I worship sincerely enough? Was that doubt evidence that I don’t believe? Is my heart in the right place?
Eventually, faith can begin to feel like constantly checking your own spiritual pulse. I don’t think that is where Jesus wants your attention. Your hope was never supposed to rest in your ability to believe perfectly. Your hope rests in Jesus.
There will be days when your faith feels strong. There will be other days when you pray something much closer to the father in Mark 9: “I believe; help my unbelief!”
Jesus didn’t reject that man for bringing Him imperfect faith. He helped him.
I think some Christians imagine Jesus standing over them with a clipboard, measuring whether their faith has finally reached an acceptable percentage. I don’t see that Jesus in the Gospels. I see people approaching Him afraid, confused, desperate, doubtful, and sometimes barely holding themselves together.
And I see Jesus continually inviting them closer.
Let What You’re Learning Become Something You Live
So keep studying. But occasionally close the book. Not the Bible. You know what I mean. Close the commentary. Pause the podcast. Put down the highlighter. And ask a simpler question.
What am I going to do with what I just learned?
If you’ve learned that God is faithful, where do you need to trust Him today? If you’ve learned that Jesus tells you to forgive, is there someone you need to begin forgiving? If you’ve learned that God cares for you, what anxiety do you need to bring honestly to Him? If you’ve learned that Jesus calls us to generosity, where can you become generous? If you’ve learned that He welcomes sinners, what are you still hiding?
Knowledge becomes incredibly powerful when truth moves from something you understand to something you begin building your life around.
That doesn’t mean earning God’s approval through obedience. It means our trust begins showing up in the way we live.
If you want to think more about that process, How Do I Know God’s Will for My Life? explores a similar idea. Much of following God isn’t decoding hidden information. It is faithfully walking with Him using what He has already revealed.
Peter’s Faith Wasn’t Finished
There is one more thing I love about Peter’s answer. This isn’t the end of Peter’s story. The man who said, “Lord, to whom shall we go?” would later deny knowing Jesus three times.
Peter still had plenty of growing left to do. His faith was real. It was also unfinished. I think we sometimes assume those two things cannot coexist.
If my faith were real, wouldn’t I be stronger? If my faith were real, wouldn’t I understand more? If my faith were real, wouldn’t I struggle less?
Not necessarily. Spiritual maturity takes time. A new believer isn’t supposed to look like someone who has walked with Jesus for forty years.
And someone who has walked with Jesus for forty years will probably tell you they still have things to learn. The goal isn’t reaching a place where you no longer need Jesus. It’s discovering, year after year, just how much you do.
So How Do I Know Whether I Have Faith?
Maybe Peter gives us one of the simplest answers. “Lord, to whom shall we go?” You may not know everything yet. You won’t. You may still have doubts. You probably will. There may be parts of Scripture you don’t understand and questions you cannot answer.
But somewhere along the way, something has begun changing.
You aren’t simply learning facts about Jesus. You’re coming to Him. You’re trusting Him with your sin. You’re bringing Him your questions. You’re trying to follow what He says. When you fail, you’re returning to Him. When you don’t understand, you’re still saying, “Where else would I go?”
That sounds an awful lot like faith to me.
So keep learning. Keep reading. Keep asking difficult questions. But don’t turn Christianity into an endless research project where you are always collecting information and never trusting the Person standing in front of you.
There is nothing wrong with studying the road. Just remember why you opened the map in the first place. Eventually, Jesus invites us to follow Him. And sometimes the clearest evidence of faith is surprisingly simple.
You keep going with Him.
