And this is eternal life, that they may know You, the only true God, and Jesus Christ whom You have sent. – John 17:3

The like living zeal and vehement desire have always been perceptible in the Church of God before any season of refreshing. Think not that Luther was the only man that wrought the Reformation. There were hundreds who sighed and cried in secret in the cottages of the Black Forest, in the homes of Germany, and on the hills of Switzerland. There were hearts breaking for the Lord’s appearing in strange places, they might have been found in the palaces of Spain, in the dungeons of the Inquisition, among the canals of Holland, and the green lanes of England. Women, as they hid their Bibles, lest their lives should be forfeited, cried out in spirit, “O God, how long?” There were pains as of a woman in travail, in secret places there were tears and bitter lamentations, on the high places of the field there were mighty strivings of spirit, and so at length there came that grand revulsion which made the Vatican to rock and reel from its foundation to its pinnacle. There has been evermore in the history of the church, the travail before there has been the result.

Even Christ went not forth to preach until He had spent nights in intercessory prayer, and uttered strong cryings and tears for the salvation of His hearers. His ministering servants who have been most useful, have always been eagerly desirous to be so. If any minister can be satisfied without conversions, he shall have no conversions. God will not force usefulness on any man. It is only when our heart breaks to see men saved, that we shall be likely to see sinners’ hearts broken. The secret of success lies in all-consuming zeal, all-subduing travail for souls.

“The love of Christ doth me constrain
To seek the wandering souls of men;
With cries, entreaties, tears, to save,
To snatch them from the fiery wave.”

~ C.H. Spurgeon
