C.S. Lewis
Human conscience reveals a universal moral law pressing upon us, exposing our inability to satisfy it and pointing beyond moral effort to a divine transformation in Jesus Christ.
The innate sense of right and wrong shared across cultures is not a social invention or herd instinct, but a prescriptive law pointing to a moral mind behind the universe.
Moral awareness creates unease because all people recognize the moral standard yet consistently fail to keep it, making forgiveness and reconciliation necessary.
Jesus Christ cannot be dismissed as merely a great moral teacher, because His explicit claims to forgive sins and possess divine authority force the logical choice between His being a fraud, a madman, or God.
