“Temporal duration is a dimension of God’s own life; in that absolutely fundamental way God is not “outside” of time. God nonetheless “transcends” time in the sense that God created those cyclic processes that make possible the measurement of time, and in the sense that temporal duration is a dimension of God’s life rather than God’s life being somehow a dimension of time.

Setting off to the side for a moment the assumption that temporal duration is indeed a dimension of God’s own life, I agree with all this. I agree that God transcends time in at least those ways. Even if temporal duration is a dimension of the divine existence, God nonetheless creates the cyclic processes that make possible the measurement of time, and temporal duration is nonetheless not itself the divine substance but “merely” a dimension of the divine life.”
