Fervourless prayer has no heart in it; it is an empty thing, an unfit vessel. Heart, soul, and life, must find place in all real praying. Heaven must be made to feel the force of this crying unto God.
Paul was a notable example of the man who possessed a fervent spirit of prayer. His petitioning was all-consuming, centered immovably upon the object of his desire, and the God who was able to meet it.
Prayers must be red hot. It is the fervent prayer that is effectual and that availeth. Coldness of spirit hinders praying; prayer cannot live in a wintry atmosphere. Chilly surroundings freeze out petitioning; and dry up the springs of supplication. It takes fire to make prayers go. Warmth of soul creates an atmosphere favourable to prayer, because it is favourable to fervency. By flame, prayer ascends to heaven. Yet fire is not fuss, nor heat, noise. Heat is intensity -- something that glows and burns. Heaven is a mighty poor market for ice.
God wants warm-hearted servants. The Holy Spirit comes as a fire, to dwell in us; we are to be baptized, with the Holy Ghost and with fire. Fervency is warmth of soul. A phlegmatic [apathetic, complacent] temperament is abhorrent to vital experience. If our religion does not set us on fire, it is because we have frozen hearts. God dwells in a flame; the Holy Ghost descends in fire. To be absorbed in God's will, to be so greatly in earnest about doing it that our whole being takes fire, is the qualifying condition of the man who would engage in effectual prayer.
Our Lord warns us against feeble praying. "Men ought always to pray," He declares, "and not to faint." That means, that we are to possess sufficient fervency to carry us through the severe and long periods of pleading prayer. Fire makes one alert and vigilant, and brings him off, more than conqueror. The atmosphere about us is too heavily charged with resisting forces for limp or languid prayers to make headway. It takes heat, and fervency and meteoric fire, to push through, to the upper heavens, where God dwells with His saints, in light.
Many of the great Bible characters were notable examples of fervency of spirit when seeking God. The Psalmist declares with great earnestness:
"My soul breaketh for the longing that it hath unto Thy judgments at all times."
What strong desires of heart are here! What earnest soul longings for the Word of the living God!
An even greater fervency is expressed by him in another place:
"As the hart panteth after the water brooks, so panteth my soul after Thee, O God. My soul thirsteth for God, for the living God: when shall I come and appear before God?"
That is the word of a man who lived in a state of grace, which had been deeply and supernaturally wrought in his soul.
Fervency before God counts in the hour of prayer, and finds a speedy and rich reward at His hands. The Psalmist gives us this statement of what God had done for the king, as his heart turned toward his Lord:
"Thou hast given him his heart's desire, and hast not withholden the request of his lips."
At another time, he thus expresses himself directly to God in preferring his request:
"Lord, all my desire is before Thee; and my groaning is not hid from Thee."
What a cheering thought! Our inward groanings, our secret desires, our heart-longings, are not hidden from the eyes of Him with whom we have to deal in prayer.
Fervency has its seat in the heart, not in the brain, nor in the intellectual faculties of the mind. Fervency therefore, is not an expression of the intellect. Fervency of spirit is something far transcending poetical fancy or sentimental imagery. It is something else besides mere preference, the contrasting of like with dislike. Fervency is the throb and gesture of the emotional nature.
It is not in our power, perhaps, to create fervency of spirit at will, but we can pray God to implant it. It is ours, then, to nourish and cherish it, to guard it against extinction, to prevent its abatement or decline. The process of personal salvation is not only to pray, to express our desires to God, but to acquire a fervent spirit and seek, by all proper means, to cultivate it. It is never out of place to pray God to beget within us, and to keep alive the spirit of fervent prayer.
Fervency has to do with God, just as prayer has to do with Him. Desire has always an objective. If we desire at all, we desire something. The degree of fervency with which we fashion our spiritual desires, will always serve to determine the earnestness of our praying.
