THE more praying there is in the world the better the world will be, the mightier the forces against evil everywhere. Prayer, in one phase of its operation, is a disinfectant and a preventive. It purifies the air; it destroys the contagion of evil. Prayer is no fitful, shortlived thing. It is no voice crying unheard and unheeded in the silence. It is a voice which goes into God’s ear, and it lives as long as God’s ear is open to holy pleas, as long as God’s heart is alive to holy things. God shapes the world by prayer. Prayers are deathless. The lips that uttered them may be closed in death, the heart that felt them may have ceased to beat, but the prayers live before God, and God’s heart is set on them and prayers outlive the lives of those who uttered them; outlive a generation, outlive an age, outlive a world. That man is the most immortal who has done the most and the best praying. They are God’s heroes, God’s saints, God’s servants, God’s vicegerents. A man can pray better because of the prayers of the past; a man can live holier because of the prayers of the past, the man of many and acceptable prayers has done the truest and greatest service to the incoming generation. The prayers of God’s saints strengthen the unborn generation against the desolating waves of sin and evil. Woe to the generation of sons who find their censers empty of the rich incense of prayer; whose fathers have been too busy or too unbelieving to pray, and perils inexpressible and consequences untold are their unhappy heritage. Fortunate are they whose fathers and mothers have left them a wealthy patrimony of prayer. The prayers of God’s saints are the capital stock in heaven by which Christ carries on His great work upon earth. The great throes and mighty convulsions on earth are the results of these prayers. Earth is changed, revolutionised, angels move on more powerful, more rapid wing, and God’s policy is shaped as the prayers are more numerous, more efficient. It is true that the mightiest successes that come to God’s cause are created and carried on by prayer. God’s day of power; the angelic days of activity and power are when God’s Church comes into its mightiest inheritance of mightiest faith and mightiest prayer. God’s conquering days are when the saints have given themselves to mightiest prayer. When God’s house on earth is a house of prayer, then God’s house in heaven is busy and all potent in its plans and movements, then His earthly armies are clothed with the triumphs and spoils of victory and His enemies defeated on every hand. God conditions the very life and prosperity of His cause on prayer. The condition was put in the very existence of God’s cause in this world. _Ask of Me_ is the one condition God puts in the very advance and triumph of His cause.
