Spurgeon said of “Uncle John” Vassar, “He was one of the few men who seemed to approach Edward Irving’s ideal of an apostolic missionary–‘a man of one thought–the gospel of Christ, of one purpose–the glory of God.’ Sublimely imprudent, as the world counts wisdom, he was wise in winning souls. His methods were unique, and his tact was inspired by the singleness of his aim and the wisdom, and energy by which he sought its realization; whole-hearted in his consecration, he was untiring in his labors, but created them.”
