If the spirit that is at work among a people is plainly observed to work so as to convince them of Christ, and lead them to him--to confirm their minds in the belief of the history of Christ as he appeared in the flesh--and that he is the Son of God, and was sent of God to save sinners; that he is the only Saviour, and that they stand in great need of him; and if he seems to beget in them higher and more honourable thoughts of him than they used to have, and to incline their affections more to him; it is a sure sign that it is the true and right Spirit; however incapable we may be to determine, whether that conviction and affection be in that manner, or to that degree, as to be saving or not.
