These living creatures in their restless, tireless, attitude after God, and their rapt devotion to His holiness, are the perfect symbols and illustrations of true prayer and its ardour. Prayer must be aflame. Its ardour must consume. Prayer without fervour is as a sun without light or heat, or as a flower without beauty or fragrance. A soul devoted to God is a fervent soul, and prayer is the creature of that flame. He only can truly pray who is all aglow for holiness, for God, and for heaven. Activity is not strength. Work is not zeal. Moving about is not devotion. Activity often is the unrecognised symptom of spiritual weakness. It may be hurtful to piety when made the substitute for real devotion in worship. The colt is much more active than its mother, but she is the wheelhorse of the team, pulling the load without noise or bluster or show. The child is more active than the father, who may be bearing the rule and burdens of an empire on his heart and shoulders. Enthusiasm is more active than faith, though it cannot remove mountains nor call into action any of the omnipotent forces which faith can command. A feeble, lively, showy religious activity may spring from many causes. There is much running around, much stirring about, much going here and there, in present-day Church life, but sad to say, the spirit of genuine, heartfelt devotion is strangely lacking. If there be real spiritual life, a deep-toned activity will spring from it. But it is an activity springing from strength and not from weakness. It is an activity which has deep roots, many and strong. In the nature of things, religion must show much of its growth above ground. Much will be seen and be evident to the eye. The flower and fruit of a holy life, abounding in good works, must be seen. It cannot be otherwise. But the surface growth must be based on a vigourous growth of unseen life and hidden roots. Deep down in the renewed nature must the roots of religion go which is seen on the outside. The external must have a deep internal groundwork. There must be much of the invisible and the underground growth, or else the life will be feeble and short-lived, and the external growth sickly and fruitless. In the Book of the prophet Isaiah these words are written: “They that wait on the Lord shall renew their strength; they shall mount up with wings as eagles; they shall run and not be weary; and they shall walk and not faint.” 40:31. This is the genesis of the whole matter of activity and strength of the most energetic, exhaustless and untiring nature. All this is the result of waiting on God.
