Who is God? Michael Reeves asserts that the essence of the fullest answer to that question is “a Trinity.” Reeves believes that while the Trinity is something many Christians shove to the back corners of their minds when it comes to relating to God, or perhaps explore with a sort of mechanical interest, with clumsy charts and worse analogies, reflecting on the Trinity is something that should stir delight in us.
Reeves quotes Karl Barth, who once said, “The triunity of God is the secret of His beauty.” Reeves contrasts the Triune God with a singular conception of God (like the Islamic understanding of God), who has a very different relationship with creation. Reeves says that “Absolutely singular supreme beings do not like creation.”
In contract, “Everything changes when it comes to the Father, Son and Spirit. Here is a God who is not essentially lonely, but who has been loving for all eternity as the Father has loved the Son in the Spirit. Loving others is not a strange or novel thing for this God at all; it is at the root of who he is.” That is to say, the relationships within the Triune God are that which defines God himself. God is relational and loving in his very essence.
