Book Two, Chapter 5: The Practical Conclusion

Lewis's last chapter of Book Two is about how new life reaches us. He compares the way this life spreads to the way ordinary life is passed on, and he names the ordinary channels: belief, baptism and Communion. At the center sits one phrase, being "in Christ." He also takes up an old objection: what about people who have never heard of Jesus?

Romans 6:3-11 is a concrete place to see this. Paul begins with a question: "Do you not know that all of us who have been baptized into Christ Jesus were baptized into his death?" The preposition matters. Not baptized near Christ or in honor of Christ, but into him. Then the picture: "We were buried therefore with him by baptism into death, in order that, just as Christ was raised from the dead by the glory of the Father, we too might walk in newness of life." Notice the aim: walking. This life is meant to show up in how you move through an ordinary Tuesday.

Life gets passed on, not manufactured. Nobody creates themselves, and Paul's logic works the same way: "if we have been united with him in a death like his, we shall certainly be united with him in a resurrection like his." The word carrying the weight is "united." Agreement with Jesus is a good start, but a student can agree with a teacher and never be changed. Union means his story becomes the story you are in. His death counts as the end of the "old self," and his resurrection becomes the ground of your new life.

Then Paul turns to practice: "So you also must consider yourselves dead to sin and alive to God in Christ Jesus." To consider is an accounting verb. You count it as so, and then you live from it. This is not pretending. It is counting what is true. Sin still shows up, but it no longer has the right to be master, because "one who has died has been set free from sin."

Where do the ordinary channels fit? Paul assumes believers know what their baptism means. For Christians through the centuries, the way into this union has run through faith, the water, and the shared meal. You don't have to invent a new spiritual technique. You show up for what Christ gave his people. If you have not been baptized, or you have drifted from Communion, that is a good next conversation with a pastor.

What about those who have never heard? Scripture gives two things to hold together. The Judge of all the earth will do what is right (Genesis 18:25), and Christians are sent to tell the good news because people need to hear it (Romans 10:14-15). Neither cancels the other. We can leave the unreached in just hands while we stay busy being messengers.

Book Two ends with Christ's life becoming ours. Next, the guide moves into Book Three and what that life looks like in everyday behavior.
