Day 9 of 28

The Perfect Penitent

Why God Became Man

Today's Reading

Read Philippians 2:5-8: "Christ Jesus, who, though he was in the form of God, did not count equality with God a thing to be grasped, but emptied himself, by taking the form of a servant, being born in the likeness of men. And being found in human form, he humbled himself by becoming obedient to the point of death, even death on a cross."

Then read Hebrews 2:14-15: "Since therefore the children share in flesh and blood, he himself likewise partook of the same things, that through death he might destroy the one who has the power of death."

Reflection

Lewis now turns to the central claim of Christianity: that God became a man, lived among us, died on a cross, and rose again — and that this somehow solves the human predicament.

He approaches the atonement with characteristic honesty, admitting that Christians have offered various theories about how the death of Christ saves us, but insisting that the fact matters more than any particular theory. The "formula," as he calls it, is simple and non-negotiable.

"We are told that Christ was killed for us, that His death has washed out our sins, and that by dying He disabled death itself. That is the formula. That is Christianity. That is what has to be believed."

But Lewis does offer a way of understanding it. Humanity, he argues, needs to repent — to surrender, to lay down arms, to undergo the painful process of unmaking our self-will. The problem is that we cannot do this properly. The very self-centeredness that needs to be surrendered is what prevents us from surrendering it. We are like a person drowning who is too panicked to cooperate with the rescuer.

"Now repentance is no fun at all... It means unlearning all the self-conceit and self-will that we have been training ourselves into for thousands of years. It means killing part of yourself."

What we need, Lewis suggests, is someone who can offer perfect repentance, perfect surrender, perfect obedience on our behalf — someone who is both fully God (and therefore capable of it) and fully human (and therefore qualified to do it for us). That is the Incarnation. That is why God became man.

Philippians 2 traces this downward movement: from the form of God, to the form of a servant, to death on a cross. Hebrews explains the purpose: by sharing in our flesh and blood, Christ entered our condition in order to defeat the enemy from the inside.

Going Deeper

Lewis is careful not to over-explain the atonement. He respects its mystery. But the core logic is clear: we owed a debt we could not pay, so God paid it Himself — not from a distance, but by entering into our situation, sharing our nature, and doing for us what we could never do for ourselves.

This is grace: not a reward for the deserving but a rescue for the helpless.

Prayer Focus

Meditating on the mystery that God Himself did for us what we could never do for ourselves

Meditation

Have you ever been in a situation where you needed help so badly that only someone outside the problem could provide it? How does that mirror the human need for a Savior?

Question for Discussion

Lewis says repentance requires 'killing part of yourself,' and the very self-centeredness that needs surrendering is what prevents us from surrendering it. Have you experienced this Catch-22 in your own spiritual life? How does the idea that Christ does for us what we cannot do for ourselves change the equation?
