The spiritual man may be compared to the physical man in a sense, or to a certain extent. The physical man demands food for its sustenance. It feasts at the breakfast table, then goes, using the strength derived in performing the vocations of life. In a few hours there will be a demand for more, as the force of the former meal is spent. “But man shall not live by bread alone.” The soul feasts upon the life of God in prayer and is strengthened, you then engage in the duties of life. In a short time you will feel the pangs of hunger in your soul. There is a longing for a deep communion with God. This is your best guide as to how often you should pray if your soul is in a good healthy state. It may not be convenient for you to go into your closet every time you feel your soul “panting after God,” but you can lift up your heart to him in the best manner you can under the circumstances, and then go and feast at your private altar at your very earliest convenience. The physical and spiritual man differ with respect to overeating. Too much food is injurious to the animal man, but the danger of surfeiting was not spoken of the soul. The inner man may feast and banquet and drink of spiritual stores and streams and the soul will grow and develop accordingly. There is but little danger of lingering too long at the feast. There is much danger of famine while the Christian as a citizen of this world has certain secular duties to perform, yet amid these he communes and walks with God. While he may be intellectually engaged in the problems of life, the higher affections of his soul live upon heavenly things. He thus drinks of the refreshing dews of glory until the beauteous graces of Christ are imbibed and infused throughout his very existence and the holy image of God is seen upon him. The effect of a prayer of faith is almost without limit. By it Daniel shut the mouths of lions. The Hebrews walked unhurt amid the flames. Elijah shut up the heavens until it did not rain for more than three years. The waters of the sea have been divided, the walls of cities thrown down, armies turned to flight, kingdoms subdued, the prison-doors opened, the barren womb has become fruitful, the lame have been made to walk, the deaf to hear, the blind to see, the dead raised to life and the soul redeemed. Oh, the wonders of prayer!
