The Shocking Alternative

Today's Scripture

Two passages anchor today: one about the choice God gives, and one about the choice Jesus forces.

Deuteronomy 30:19 — "I call heaven and earth to witness against you today, that I have set before you life and death, blessing and curse. Therefore choose life, that you and your offspring may live."

Mark 2:5-7 — "And when Jesus saw their faith, he said to the paralytic, 'Son, your sins are forgiven.' Now some of the scribes were sitting there, questioning in their hearts, 'Why does this man speak like that? He is blaspheming! Who can forgive sins but God alone?'"

The Big Idea

Today Lewis answers two of the biggest questions a person can ask. First: if God is good, why did he make a world where evil was even possible? Because love requires freedom. Second: who is Jesus, really? Someone who made claims so enormous that "nice moral teacher" is the one thing he cannot be.

Reflection

The dangerous gift

Start with the question every honest person eventually asks: if God made everything, why is there so much wrong with everything?

Lewis's answer begins with a simple observation about freedom:

"If a thing is free to be good it is also free to be bad. And free will is what has made evil possible. Why, then, did God give them free will? Because free will, though it makes evil possible, is also the only thing that makes possible any love or goodness or joy worth having." — C.S. Lewis, Mere Christianity

Think about it on a small scale. Imagine a friend who is only your friend because a chip in their brain forces them to be. Every kind word is programmed. Every loyalty is automatic. Would that friendship mean anything? Of course not. The only love worth having is love that could have been withheld — and was given anyway.

That is why God says, "I have set before you life and death... therefore choose life" (Deuteronomy 30:19). He does not say, "I have wired you for life." He sets two roads in front of his people and pleads with them to take the right one. Joshua does the same at the end of his life: "Choose this day whom you will serve... But as for me and my house, we will serve the Lord" (Joshua 24:15). From the very beginning, God has wanted choosers, not machines.

But a real choice means a real risk. And in Genesis 3:4-6, the risk goes wrong. The serpent's bait is worth reading slowly: "You will be like God." Lewis says that is still the bait, every time:

"The moment you have a self at all, there is a possibility of putting yourself first — wanting to be the centre — wanting to be God, in fact." — C.S. Lewis, Mere Christianity

Every sin you have ever committed is a version of that one move. Cheating puts your grades at the center. Gossip puts your reputation at the center. Even worry, oddly enough, puts your control at the center. Augustine taught the church to see that evil is not really a "thing" God created at all — it is good, bent; a hole where good should be:

"For what is that which we call evil but the absence of good?" — Augustine, Enchiridion

Rust needs iron. Rot needs wood. Evil needs good to corrupt. God made the iron; we supplied the rust.

Why the machine only runs on God

Here is where Lewis takes the argument somewhere surprisingly practical. If we were made by God and for God, then trying to be happy without him is not just naughty — it is impossible, like trying to run a car on seawater.

"God cannot give us a happiness and peace apart from Himself, because it is not there. There is no such thing." — C.S. Lewis, Mere Christianity

Read that twice, because it explains most of human history and most of your last bad week. The reason money, popularity, romance, and achievement keep disappointing us is not that they are evil. It is that we keep asking them to be God, and they keep buckling under the weight. A.W. Tozer said the deepest thing about any of us is what we put in that center spot:

"What comes into our minds when we think about God is the most important thing about us." — A.W. Tozer, The Knowledge of the Holy

Whatever sits at the center of your life is functionally your god. Lewis's point is that only one God fits the socket.

The king has landed

So the world has gone wrong through misused freedom, and its people keep bowing to substitutes. What is God's response? Lewis's answer is one of the most thrilling pictures he ever drew:

"Enemy-occupied territory — that is what this world is. Christianity is the story of how the rightful king has landed, you might say landed in disguise, and is calling us all to take part in a great campaign of sabotage." — C.S. Lewis, Mere Christianity

Notice what this picture does. It takes seriously how bad things are — the world really is occupied, bent, ruled in a thousand places by pride and cruelty. But it refuses despair, because the story is not over. The rightful king has not written off his territory. He has landed — quietly, as a baby in a barn in an occupied province, behind enemy lines.

John says this is exactly what Christmas was: "The reason the Son of God appeared was to destroy the works of the devil" (1 John 3:8). Not to give the occupied territory better advice. To end the occupation. And Paul describes what happens to every person the king reclaims: "He has delivered us from the domain of darkness and transferred us to the kingdom of his beloved Son" (Colossians 1:13). Transferred — carried across the lines, citizenship changed.

But why a disguise? Why doesn't God simply land in force, end the whole rebellion in an afternoon? Lewis's answer loops back to where today began: free will. A God who arrived in overwhelming, undeniable glory would leave no room for anyone to choose him — you do not choose the sun at noon; you just squint.

"When the author walks on to the stage the play is over." — C.S. Lewis, Mere Christianity

God is delaying the open landing to give every one of us the chance to join the right side freely, while joining still means something. In the meantime, every honest word in a culture of spin, every kindness in a hallway of mockery, every secret act of obedience is what Lewis calls sabotage — a small strike of the coming kingdom, behind the lines of the present one.

A king landing in disguise, though, raises the obvious question: how would we recognize him? What did the disguised king actually say about himself? That is where the chapter turns — and where the disguise comes off.

The claims that break the "nice teacher" theory

So the world is full of people worshiping substitutes. What does God do about it? He arrives in person. And this is where Lewis springs his famous trap.

Many people want to say something polite about Jesus: wonderful teacher, beautiful life, wise sayings — but not God. Lewis asks us to actually listen to what Jesus said. In Mark 2, Jesus tells a paralyzed man, "Your sins are forgiven." The scribes are scandalized — "Who can forgive sins but God alone?" — and notice that their logic is perfect. You can forgive a wrong done to you. Only God can forgive wrongs done against everyone and everything, because every sin is finally against him.

In John 8:58-59, Jesus says, "Before Abraham was, I am" — taking the divine name God spoke from the burning bush and putting it on his own lips. The crowd picks up stones, because they understand exactly what he means. In John 10:30-33, he says, "I and the Father are one," and again the stones come out: "you, being a man, make yourself God." And in John 14:6 he claims, "I am the way, and the truth, and the life. No one comes to the Father except through me." Not a way. The way.

A merely human being who talks like this is not a wise teacher having a good day:

"'I'm ready to accept Jesus as a great moral teacher, but I don't accept his claim to be God.' That is the one thing we must not say. A man who was merely a man and said the sort of things Jesus said would not be a great moral teacher." — C.S. Lewis, Mere Christianity

Lewis says such a man would be deluded — or something far worse. Either way, the middle ground people want, admiring Jesus while ignoring his claims, is the one square on the board Jesus deliberately removed:

"Let us not come with any patronising nonsense about His being a great human teacher. He has not left that open to us. He did not intend to." — C.S. Lewis, Mere Christianity

You can dismiss him. You can fall at his feet. The one thing you cannot honestly do is pat him on the head.

The question that will not stay theoretical

Which brings the whole chapter to a point — and the point is aimed at you. Jesus once turned to his friends and made it personal: "'But who do you say that I am?' Simon Peter replied, 'You are the Christ, the Son of the living God'" (Matthew 16:15-16).

Notice that Jesus did not ask, "What do the crowds say?" He asked Peter. And here is the gospel hiding inside today's hard logic: the same Jesus who would not let us call him merely a teacher came on purpose, into our rebel world, to do for us what no teacher could. Teachers hand you advice; you still have to do the climbing. This man handed the paralytic forgiveness before he handed him his legs — because forgiveness was the deeper paralysis. The shocking alternative turns out to be shockingly good news: God did not send a message. He came himself, into territory that had chosen against him, to win back the choosers. Starting with you.

Going Deeper

Sometime today, ask one person you trust, "Who do you think Jesus was?" Just listen. Then notice which option they pick — teacher, legend, madman, Lord — and gently ask the Lewis question: "Can a merely human being say the things he said and still be good?" You are not trying to win an argument. You are doing for them what Jesus did for Peter: turning a crowd question into a personal one.
