John 3:5
Jesus answered, 'Very truly I tell you, no one can enter the kingdom of God unless they are born of water and Spirit' — the cryptic reference to water and Spirit elicits considerable interpretive debate: water may refer to baptism, physical birth, or Torah cleansing. The essential point remains: birth requires both material (water) and spiritual (pneuma) dimensions, neither alone sufficing. The combined condition establishes that divine regeneration involves the whole person.
