No doubt the expectation of spiritual benefit from the waters of the Jordan is one cause of the annual pilgrimage thither, and of the strange scene that presents itself when the pilgrims are bathing. It seems impossible for man, except under the influence of the strongest spiritual views, to avoid the belief that somehow mechanical means may give rise to spiritual results. There is nothing from which he is naturally more averse than spiritual activity. Any amount of mechanical service he will often render to save him from spiritual exercise. Symbols without number he will willingly provide, if he thereby escape the necessity of going into the immediate presence of God, and worshipping Him who is a Spirit in spirit and in truth. But can mechanical service or material symbols be anything but an evil, if the would-be worshipper is thereby prevented from recognising the necessity of a heart-to-heart fellowship with the living God? Must we not be in living touch with God if the stream of Divine influence is to reach our hearts, and we are to be changed into His image? In the Psalms, which express the very essence of Hebrew devotion, spiritual contact with God is the only source of blessing. "O God, Thou art my God; early will I seek Thee: my soul thirsteth for Thee, my flesh longeth for Thee in a dry and thirsty land, where there is no water. To see Thy power and Thy glory, so as I have seen Thee in the sanctuary."
Thus it was that by God's prescription the twelve plain stones taken out of the Jordan were the only memorial of the great deliverance. There was no likeness on them of the Divine Being by whom the miracle had been performed. There was nothing to encourage acts of reverence or worship directed toward the memorial. Twelve rough stones, with no sculptured figures or symbols, not even dressed by hammer and chisel, but simply as they were taken out of the river, were the memorial. They were adapted for one purpose, and for one only: "When your children shall ask their fathers in time to come, saying, What mean these stones? then ye shall let your children know, saying, Israel came over this Jordan on dry land. For the Lord your God dried up the waters of the Jordan from before you, until ye were passed over, as the Lord your God did to the Red Sea, which He dried up from before us, until we were gone over: that all the people of the earth might know the hand of the Lord, that it is mighty: that ye might fear the Lord your God for ever."
