There is a spirit in man; and the inspiration of the Almighty giveth them understanding.
Job xxxii. 8.

If ye then, being evil, know how to give good gifts unto your children; how much more shall your heavenly Father give the Holy Spirit to them that ask Him?
Luke xi. 13.

IS it supposable that God has permitted personal intercourse between man and man to be such a potent instrument in the building up of character, and yet has made all intercourse with Himself impossible? If the spirit of man can, through the power of influence and sympathy, bless and uplift the spirit of his fellow-man, much more, a thousand-fold more, shall God who, be it remembered, is a Spirit also, aid by intercourse and influence the creature spirit whom He permits to call himself His child.
William Reed Huntington.

In the fellowship which is established in prayer between man and God we are brought into personal union with Him in whom all things’have their being. In this lies the possibility of boundless power; for when the connection is once formed, who can lay down the limits of what man can do in virtue of the communion of his spirit with the Infinite Spirit?
