I have often been struck with this circumstance in the mode of preaching, that nothing was heard of the danger of spurious [false] conversion. For months together, the thought never seemed to be glanced at, that there was any such thing as a satanic influence…an enthusiastic hypocrite, or a self-deceived person, never to be once dreamed of (Asahel Nettleton, D.D., quoted in Bennet Tyler and Andrew Bonar, The Life and Labours of Asahel Nettleton, The Banner of Truth Trust, 1975 reprint, pp. 367-368).
