Doing something involuntarily or merely because we "have always done it that way" can dig a rut. It is performance without thinking. It would be like waking up each morning and praying the same prayer without inspiration. In Christian Science, God is known as Mind, the all-knowing intelligence, the only source of power. Man is His reflection; he expresses divine intelligence. God's man is always conscious, spontaneous, free.
Why should we want to change faulty concepts, to think intelligently and correctly, to move out of the merely habitual? Is it not to glorify our heavenly Father, to demonstrate man's spiritual dominion and spontaneity, and to be able to live more joyful, successful, and useful lives?
We need especially to be rid of bad habits. They clutter our days. Sometimes students of Christian Science may feel they don't really have any bad habits. They have learned spiritual lessons and made the choice not to drink alcoholic beverages, smoke, take drugs, use obscene language, or gamble, for example. Yet can't we all, if we honestly examine our actions, recognize something we habitually do that we need to eliminate from our experience so that we may more purely express Soul? The habit may be something we are willing to acknowledge as undesirable but still accept as part of our life style. Or the habit may be something we are not even aware of and from which we need to be awakened.
