Arthur Walkington Pink was an English Christian evangelist and biblical scholar who was known for his staunchly Calvinist and Puritan-like teachings in an era dominated by opposing theological traditions. Pink was one of the most influential evangelical authors in the second half of the twentieth century. "This time we take up our pen to write on one of the most solemn truths taught in the Word. And ere we began we turned to the Lord and earnestly sought that wisdom and grace which we are conscious we sorely need; making request that we might be preserved from all error in what we shall say, and that nothing may find a place in these pages which shall be displeasing to that Holy One, “whose we are, and whom we serve.†O that we may write in the spirit of One who said, “Who knoweth the power of Thine anger, even according to Thy fear, so is Thy wrath†(Psalm 90:11). The subject before us is one that needs stressing in these days. The great majority of our pulpits are silent upon it, and the fact that it has so little place in modern preaching is one of the signs of the times, one of the many evidences that the Apostasy must be near at hand. It is true that there are not a few who are praying for a world-wide Revival, but it appears to the writer that it would be more timely, and more scriptural, for prayer to be made to the Lord of the harvest, that He would raise up and thrust forth laborers who would fearlessly and faithfully preach those truths which are calculated to bring about a revival."
