Though complete in trinitarian fullness, God does not choose to be alone. Barth says, “God wills and posits the creature, neither out of caprice nor necessity, but because he loved it from eternity, because he wills to demonstrate his love for it, and because he wills, not to limit his glory by its existence and being, but to reveal and manifest it in his own co-existence with it.” God is bound together with us by choice. This is why he acts in history and relates to creatures. He loves to exist in dynamic relationship with the world. God has pledged himself to this situation so full of promise and of risk. The love of God grounds creation. His purpose for it has always been union and communion. God loved the world before it fell into sin. His initial relationship with it was not a legal but a loving one.
