Substantively speaking, God is not a person. And yet, God can only be interacted with as if God were a person.
Paul Tillich was right: if God is the one in which we live and move and have our being–if God is the very ground, structure, and goal of being–then God is not a being. God cannot be subject to the particulars of being for God is the one that determines those particulars.
And yet, in a poetic way, we claim that God has revealed God’s very self to us–the nature of God. We see evidence of God in nature, which shows us much about God, but it is Jesus Christ whom we claim shows us what it is that God intends.
Jesus Christ–a person–shows us how God–a not-person–intends for us to love all of Creation.
