One of my favorite authors is Dallas Willard. He has an uncommon ability to articulate concepts in a way that helps you connect with them. In his book The Divine Conspiracy, he reflects on what it means when Jesus says I have come so that you might have life (John 10:10):
Jesus offers himself as God’s doorway into 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 might have life, and life to the limit.”
