Sabbath time is a time when we turn our attention to what is holy, to what is sacred, to what is important. It's a time when we allow the clamor of the world to fall away and we listen for the still, small voice of God. It's a time when we allow ourselves to be embraced by the love of God, to rest in that love, and to be renewed and refreshed by it.
When Mother Teresa was asked what would happen to her congregation after she had gone, she is said to have responded:
"A person emptier than myself will come along."
The implication here is that the greatness of a person lies in the depth of his or her own self-emptying. Another implication is that what is emptied of oneself will be filled with the self of God. Poverty as a chosen life-style is precisely this:
"To empty oneself of all that one is and has so that all will be at the disposal of the Lord."
