Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God.
The invisible birth of which John speaks is an act of God. John is talking about something beyond the physical birth that we know. The senses can touch the physical birth. When we were born into this world, those around us could see and feel and hold and weigh us. They could wash and clothe and feed us.
But this invisible, mysterious birth of which John speaks has nothing to do with the flesh. It is of heaven. This birth is of the Spirit—a birth of another kind, a mystical birth….
If Jesus our Lord had talked merely about people being born physically into the world, He would never have been heard, and His teachings would not have been preserved in print. Physical birth is too common—everyone is born. But these people experienced a birth not of the body but of the heart. They were born not into time but into eternity. They were born not of earth but of heaven. They had an inward birth, a spiritual birth, a mysterious birth, a mystical birth! FBR005-006
God is in all things as being, as activity, as power. God gives birth in the soul alone, for though every creature bears God’s mark, the soul is the natural image of God. BME013
