The Case for Christianity — Why This Series Exists

Series: Know What You Believe and Why — Track 3
The Man Who Could Not Answer
I know a man — a good man, a faithful man, someone who has been in church his entire life — who was sitting at a dinner table a few years ago when his college-age son looked at him and asked a simple question: "Dad, why do you actually believe this is true?"
He told me later that he sat there for a long moment and realized he did not have an answer. Not a real one. He had feelings. He had experiences. He had a lifetime of Sunday mornings and vacation Bible school and small group meetings. What he did not have was a reason — a clear, defensible, intellectually honest answer to the most important question his son had ever asked him.
His son is not in church anymore.
I am not telling that story to make anyone feel guilty. I am telling it because it is not unusual. It is, in my experience, closer to the norm than the exception. Most Christian men can tell you what they believe. Far fewer can tell you why — in a way that would satisfy a skeptic, answer a Muslim, or hold up under the pressure of a college philosophy class.
That is the gap this series exists to close. Not because faith is primarily an intellectual exercise. It is not. But because the God who made the human mind did not ask us to park it at the door when we walk into church. And because the men who are leaving the faith — and the sons who are never entering it — deserve better than feelings and tradition.
The case for Christianity is strong. Stronger than most Christians know. This track lays it out.
What We Are Arguing
Let me be clear about what this series is and is not.
It is not an argument that Christianity is emotionally satisfying, culturally beneficial, or personally meaningful — though it is all of those things. It is an argument that Christianity is true. That the events it describes actually happened. That the God it proclaims actually exists. That the resurrection of Jesus Christ is a historical fact that can be examined, tested, and defended on the same evidentiary grounds as any other historical claim.
This matters because the alternative — a faith that rests entirely on personal experience and cannot survive contact with honest questions — is not a faith worth having. It is a comfort blanket. And comfort blankets do not hold up when your son asks you why you believe, when your colleague tells you the Bible is full of contradictions, or when you are lying awake at three in the morning wondering if any of it is real.
The Christian faith does not ask you to believe in spite of the evidence. It asks you to look at the evidence and follow it where it leads.
The Four Lines of Evidence
This track covers four primary lines of evidence for the truth of Christianity. Each one is the subject of its own article. Together they build a cumulative case that is, in the judgment of serious historians and philosophers — including many who are not Christians — among the strongest cases for any ancient historical claim.
The manuscript evidence. The Bible is the most extensively documented ancient text in existence. The number of manuscripts, the earliness of the manuscripts, and the consistency across manuscripts is unmatched by any other ancient document. If you trust the works of Caesar, Plato, or Tacitus — and historians do — you have no rational basis for dismissing the New Testament on manuscript grounds.
The archaeological evidence. For two centuries, critics of the Bible argued that its historical claims were legendary — that the people, places, and events it described were invented. Archaeology has repeatedly vindicated the biblical record. People and places once dismissed as fictional have been confirmed by the spade. The pattern is consistent enough to be significant.
The prophecy evidence. The Hebrew Bible contains hundreds of specific, verifiable prophecies about the Messiah — written centuries before Jesus was born — that were fulfilled in His life, death, and resurrection. The mathematical probability of this occurring by chance is not a matter of faith. It is a matter of arithmetic.
The resurrection evidence. The resurrection of Jesus Christ is the central claim of Christianity and the most examined event in ancient history. The evidence for it — the empty tomb, the post-resurrection appearances, the transformation of the disciples, the conversion of Paul and James — is historical evidence that has been examined by skeptics for two thousand years and has not been successfully refuted.
A Word About Doubt
Before we go further, a word about doubt — because this series is not just for men who want to defend their faith against outside attack. It is also for men who are not sure what they believe, who have questions they have never felt safe asking, who have been told that doubt is the opposite of faith and have therefore carried their questions alone.
Doubt is not the opposite of faith. Intellectual dishonesty is the opposite of faith. A man who has genuine questions and pursues honest answers is doing something more faithful than a man who suppresses his questions because the answers might be uncomfortable.
The Christian faith has been examined by some of the sharpest minds in human history — Augustine, Aquinas, Pascal, Lewis, Chesterton, Plantinga — and it has not collapsed under the examination. It has deepened. The questions are worth asking. The answers are worth knowing.
Ask the questions. Follow the evidence. That is what this track is for.
Practical Applications
Know the four lines of evidence. Manuscripts. Archaeology. Prophecy. Resurrection. These are the four pillars of the intellectual case for Christianity. By the end of this track, you should be able to give a basic account of each one in a conversation.
Read one apologetics book this year. C.S. Lewis's Mere Christianity. Lee Strobel's The Case for Christ. N.T. Wright's The Resurrection of the Son of God. Tim Keller's The Reason for God. Pick one. Read it. The investment is small. The return is significant.
Have the conversation with your kids before someone else does. The college campus, the internet, and the culture are having the conversation about whether Christianity is true whether you are or not. A man who prepares his children for that conversation is doing one of the most important things a father can do.
Stop treating intellectual questions as spiritual threats. A question about the reliability of the Bible is not an attack on God. It is an invitation to go deeper. Treat it that way.
The Closing Charge
The man at the dinner table who could not answer his son's question is not a bad man or a weak Christian. He is a man who was never given the tools. This series is the tools.
The case for Christianity is not a case built on blind faith, cultural tradition, or emotional experience — though all of those things have their place. It is a case built on manuscripts and archaeology and fulfilled prophecy and an empty tomb that nobody in the first century could explain away despite having every reason to try.
Know the case. Own it. Be ready to make it.
Your son is going to ask.
