John knows … that God is love, and God’s endless love spills out in creation through the Word. That love is revealed and commanded in Torah, distilled in the life, teaching, death, and resurrection of Jesus, and now enlivened by the Spirit in the church. When Christians experience union with God and each other, the very love that precedes, sources, and invades creation in the Son is reincarnated; it is instantiated in what Paul called the “body of Christ.”
