Self-giving love is the dynamic currency of the trinitarian life of God. The persons within God exalt each other, commune with each other, defer to one another. Each person, so to speak, makes room for the other two. I know it sounds a little strange, but we might almost say that the persons within God show each other divine hospitality.
