Eternal life—we tend to think of it in terms of existence that never comes to an end. And the existence it seems to imply—a sort of religious experience in the sky—leaves us wondering if we would want it to go on forever. But Jesus is quite clear that when he speaks of eternal life, what he means is life that is absolutely wonderful and can never be diminished or stolen from you. He says, "I have come that they may have life, and have it to the full" (John 10:10). Not, "I have come to threaten you into line," or "I have come to exhaust you with a long list of demands." Not even, "I have come primarily to forgive you." But simply, My purpose is to bring you life in all its fullness. Dallas Willard writes in The Divine Conspiracy:
Jesus offers himself as God's doorway into the life that is truly life. Confidence in him leads us today, as in other times, to become his apprentices in eternal living. "Those who come through me will be safe," he said. "They will go in and out and find all they need. I have come into their world that they may have life, and life to the limit."
In other words, eternal life is not primarily duration but quality of life, "life to the limit." It cannot be stolen from us, and so it does go on. But the focus is on the life itself. "In him was life," the apostle John said of Jesus, "and that life was the light of men" (John 1:4).
