In his book Three Mile an Hour God, the late Japanese theologian Kosuke Koyama put this language around it:
God walks “slowly” because he is love. If he is not love he would have gone much faster. Love has its speed. It is an inner speed. It is a spiritual speed. It is a different kind of speed from the technological speed to which we are accustomed. It is “slow” yet it is lord over all other speeds since it is the speed of love. (Location 345)
