The crisis which separates these two experiences is the enlargement of the heart. This is a figure for what St. John calls "perfect love," and which St. Paul elsewhere describes as "the love of God shed abroad in the heart by the Holy Ghost," though he once, at least, employs the Old Testament phrase: "O ye Corinthians, my mouth is opened unto you, my heart is enlarged." Reverse the order of these clauses, and we have the cause and the effect. A full heart makes an unloosed tongue.
The inquiry is all-important, When is this crisis reached? Some say "Never this side the dying bed." But no Scripture proof of this dismal doctrine is ever given. It. is not true that the believing soul must be a partly filled goblet till it is over flowed by the waters of the river of death. Others, say: All souls at the new birth are deluged with love to the brim, a love that drives chariot wheels as swiftly as the mysterious electric current drives our street-car, up and down our tri-mountain city, Such a steady motive power is not the experience of multitudes, yea, the vast majorities who are truly regenerate. Their inertia is great and the impelling power is feeble. Indeed, something worse than inertia is to be overcome; a strong opposition often arises within, which it takes all their strength to overcome. They have not a heart at leisure from itself to concentrate upon the work of God. True it is that a few Christians, like John Fletcher, very soon after their birth into the kingdom, because of a correct apprehension of their privilege in the dispensation of the Spirit, are deluged with divine love and become giants in faith. The mass of believers are mere babes in spiritual development. They see days of great weakness and are often on the verge of surrender to the foe. Some, alas, throw away their arms and run away from the fight and never renew the battle. Others fight all their lives with foes in their own hearts and never overcome and cast them out. They have been told by their preachers that this war in the members is the normal Christian life. Hence, believing their preachers instead of the Word of God, they limit His power by their unbelief, and never gladly run, but always sadly drag themselves along the heavenly way.
Again, the growing failure to magnify the Holy Spirit results in constraint and the legal spirit, instead of the freedom of the evangelical spirit, inspiring courage to run through troops of foes. How many so-called evangelical Christians there are whose creed is practically as defective as was that of the first believers in Ephesus: "We have not so much as heard whether there be any Holy Ghost" as receivable into the heart.
This important item dropped out of a Christian's faith palsies his tongue, paralyzes his hands and enfeebles his feet. If he is a preacher, his message will be delivered in the weakness of uncertainty and doubt,. Splendid rhetoric and oratorical tones and attitudes tire beggarly substitutes for the unction of the Holy Ghost. The anointed pulpit will always be mighty. The Spirit inspires fearlessness, imparts freedom of utterance, enkindles zeal and unconquerable love of souls. All of those are elements of genuine eloquence. They furnish the man, the subject and the occasion.
The formal prayer meeting would be transformed by the enlargement of the heart. Dumbness, the penalty of unbelief (Luke i. 20 ), will find it ready and glad utterance, and the dry harangue will be replaced by the hallelujah.
Let the heart of Protestantism be enlarged by the fulness of the Comforter, and rivers of salvation would flow out unto the ends of the earth, vitalizing those which have been devised as substitutes for His regenerating and sanctifying power.
