The oldest argument: a changed life
Evidence for Christianity: changed lives
Long before the modern apologetics shelf, the faith made its case through the lives it changed — and most tellingly through the skeptics and opponentswho set out against it and were won. These are first-person accounts of exactly that: reason, resistance, and transformation, free to read in the public domain and offered here as clean editions.

Questions about the evidence of changed lives
- What is the argument from changed lives?
- It's one of the oldest and most practical arguments for Christianity: the faith's power is shown in the lives it transforms — especially the lives of skeptics, scholars, and outright opponents who set out against it and were won. A changed life is evidence you can read firsthand.
- Are these good books for studying apologetics?
- They're a complement to the argument-based apologetics of writers like Lewis or Chesterton. Where those make the case, these show the result: primary-source accounts of real people reasoning, resisting, and being changed. Good for a class or group studying the evidence for the faith.
- Which is the best example of a skeptic converted?
- George Romanes is the sharpest case — Darwin's own friend and correspondent, who published an anonymous case against theism as a young man and spent his last years working his way back. Thomas Halyburton answered the deists; Augustine came through the philosophies; and Imad-ud-din, a Muslim scholar, was won while trying to refute Christianity.
