Her point is that we think of "sacred times" when God is present and active and "secular times" when he is not. Thus, we relegate whatever is mundane, earthy and boring to the "secular" and miss God. Since each moment is truly God-saturated and there is in reality no separation, what makes the "sacred" times different from the "secular" ones? "The difference," she says, "is our openness to his presence and our willingness to walk in awareness of God" (p.188-9).
I'm trying to fight the tendency today to settle for a workday devoid of God. I'm going to try to see each moment as sacrament, and to practice the presence of God.
