In an era when the fourth commandment seems arcane, Heschel creates an acute sense of urgency towards our awareness of the Sabbath...its preciousness, its relavance. For we must choose: are we to be workaholic slaves to the Pharaoh of material aquisition, or serve precious moments of holiness, which the Sabbath provides? In a society that values things more than moments of time, Heschel shows us how the Sabbath points us to a value system in which time, when made holy, puts space/things/people in their proper perspective. Have we become deluded that time-saving devices(cars, microwaves, telephones, computers) will create new moments of time for us? The opposite has proved true. As Heschel says, "The more we think the more we realize:we cannot conquer time through space. We can only master time in time." And so he shows us that God's gift to us is not arcane, but critically important today. As the Sabbath is the central Jewish holiday, and the first of all that God created as 'holy', we take a new view of Judaisim- its main holy sites are architectural masterpieces made from time, holy days set in the cycle of a week, a season, a year. And these lessons are for every religion, for our understanding of the value of time needs to be universal, or we fall into a materialism in which there is no room for religion or spirituality. There are so many teachings from Heschel in each paragraph and his language constantly brushes the edges of poetry. "The higher goal of spiritual living is not to amass a wealth of information, but to face sacred moments. In a religious experience, for example, it is not a thing that imposes itself on man but a spiritual presence. What is retained in the soul is the moment of insight rather than the place where the act came to pass. A moment of insight is a fortune, transporting us beyond the confines of measured time. Spiritual life begins to decay when we fail to sense the grandeur of what is eternal in time" Abraham Heschel, THE SABBATH.
