Prayer has to do with the entire man. Prayer takes in man in his whole being, mind, soul and body. It takes the whole man to pray, and prayer affects the entire man in its gracious results. As the whole nature of man enters into prayer, so also all that belongs to man is the beneficiary of prayer. All of man receives benefits in prayer. The whole man must be given to God in praying. The largest results in praying come to him who gives himself, all of himself, all that belongs to himself, to God. This is the secret of full consecration, and this is a condition of successful praying, and the sort of praying which brings the largest fruits.
The men of olden times who wrought well in prayer, who brought the largest things to pass, who moved God to do great things, were those who were entirely given over to God in their praying. God wants, and must have, all that there is in man in answering his prayers. He must have whole-hearted men through whom to work out His purposes and plans concerning men. God must have men in their entirety. No double-minded man need apply. No vacillating man can be used. No man with a divided allegiance to God, and the world and self, can do the praying that is needed.
Holiness is wholeness, and so God wants holy men, men whole-hearted and true, for His service and for the work of praying. “And the very God of peace sanctify you wholly; and I pray God your whole spirit and soul and body be preserved blameless unto the coming of our Lord Jesus Christ.” These are the sort of men God wants for leaders of the hosts of Israel, and these are the kind out of which the praying class is formed.
Man is a trinity in one, and yet man is neither a trinity nor a dual creature when he prays, but a unit. Man is one in all the essentials and acts and attitudes of piety. Soul, spirit and body are to unite in all things pertaining to life and godliness. The body, first of all, engages in prayer, since it assumes the praying attitude in prayer. Prostration of the body becomes us in praying as well as prostration of the soul. The attitude of the body counts much in prayer, although it is true that the heart may be haughty and lifted up, and the mind listless and wandering, and the praying a mere form, even while the knees are bent in prayer.
