He would have us "come boldly to the throne of grace" with a well-reasoned and Scriptural understanding of what we desire, and with a purpose to "ask," "seek," and "knock" till we get the thing we wish, being assured that it is according to His will; and this boldness is not inconsistent with the profoundest humility and a sense of utter dependence; indeed, it is always accompanied by self-distrust and humble reliance upon the merits of Jesus, else it is but presumption and unsanctified conceit. This union of assurance and humility, of boldness and dependence, can be secured only by the baptism with the Holy Spirit, and only so can one be prepared and fitted for such prayer. Three great obstacles hinder mighty prayer: 1. selfishness; 2, unbelief; 3, the darkness of ignorance and foolishness. The baptism with the Spirit sweeps away these obstacles and brings in the three great essentials to prayer--1, faith; 2, love, Divine love; 3, the light of heavenly knowledge and wisdom. 1. Selfishness must be cast out by the incoming of love. The ambassador must not be seeking personal ends, but the interests of his government and the people he represents; the son must not be seeking private gain, but the common prosperity of the partnership in which he will fully and lawfully share; the bride must not forget him to whom she belongs, and seek separate ends, but in all ways identify herself with her husband and his interests. So the child of God must come in prayer, unselfishly. It is the work of the Holy Spirit, with our co-operation and glad consent, to search and destroy selfishness out of our hearts, and fill them with pure love to God and man. And when this is done we shall not then be asking for things amiss to consume them upon our lusts, to gratify our appetites, or pride, or ambition, or ease, or vain-glory. We shall seek only the glory of our Lord and the common good of our fellow-men, in which, as co-workers and partners, we shall have a common share. If we ask for success, it is not that we may be exalted, but that God may be glorified; that Jesus may secure the purchase of His blood; that men may be saved, and the Kingdom of Heaven be established upon earth. If we ask for daily bread, it is not that we may be full, but that we may be fitted for daily duty. If we ask for health, it is not alone that we may be free from pain and filled with physical comfort, but that we may be spent "in publishing the sinner's Friend," in fulfilling the work for which God has placed us here.
