When people - in this case, women - neglect the use of their minds, they may get caught up in idle activities, too many activities, silly reading and leisure habits which lead, finally, to a shallow understanding of what it means to live the Christian life. Their faith may also be too thin to sustain them in the hardships that invariably accompany the average existence.
Their Christian understanding, undeepened by knowledge, may become boring whether they admit it or not. As J.I. Packer says in his popular book Knowing God, "The world becomes a strange, mad, painful place, and life in it a disappointing and unpleasant business for those who do not know about God. Disregard the study of God, and you sentence yourself to stumble and blunder through life, blindfolded, as it were, with no sense of direction, and understanding of what surrounds you. This way you can waste your life, and lose your soul" (pp. 14-15).
