"Theologian Kosuke Koyama presses this notion of appropriate speed even further. He suggests that some things God can teach us only very slowly, at the pace of walking, the speed of life. He marvels that Israelites needed forty years of trekking through the desert. They learned "the word of God in the wilderness as they walked three miles an hour” with “the three mile an hour God.""
