"There is _none_ that calleth upon Thy name, that stirreth himself to take hold of Thee."--ISA. lxiv. 7. "And I sought for a man that should stand in the gap before Me for the land, that I should not destroy it; but _I found none_."--EZEK. xxii. 30. "I chose you, and appointed you, that ye should go and bear fruit: that whatsoever ye shall ask of the Father in My name, He may give it you."--JOHN xv. 16. In the study of the starry heavens, how much depends upon a due apprehension of magnitudes. Without some sense of the size of the heavenly bodies, that appear so small to the eye, and yet are so great, and of the almost illimitable extent of the regions in which they move, though they appear so near and so familiar, there can be no true knowledge of the heavenly world or its relation to this earth. It is even so with the spiritual heavens, and the heavenly life in which we are called to live. It is specially so in the life of intercession, that most wondrous intercourse between heaven and earth. Everything depends upon the due apprehension of magnitudes. Just think of the three that come first: There is a world, with its needs entirely dependent on and waiting to be helped by intercession; there is a God in heaven, with His all-sufficient supply for all those needs, waiting to be asked; there is a Church, with its wondrous calling and its sure promises, waiting to be roused to a sense of its wondrous responsibility and power. _God seeks intercessors._--There is a world with its perishing millions, with intercession as its only hope. How much of love and work is comparatively vain, because there is so little intercession. A thousand millions living as if there never had been a Son of God to die for them. Thirty millions every year passing into the outer darkness without hope. Fifty millions bearing the Christian name, and the great majority living in utter ignorance or indifference. Millions of feeble, sickly Christians; thousands of wearied workers, who could be blessed by intercession, could help themselves to become mighty in intercession. Churches and missions sacrificing life and labour often with little result, for lack of intercession. Souls, each one worth more than worlds, worth nothing less than the price paid for them in Christ's blood, and within reach of the power that can be won by intercession. We surely have no conception of the magnitude of the work to be done by God's intercessors, or we should cry to God above everything to give from heaven the spirit of intercession.
