"These manifestations that have been mentioned are the best that mankind can have; and they are such as oblige Christians entirely to embrace professors as saints, and love them and rejoice in them as the children of God, and are sufficient to give them a great satisfaction concerning them, as ever is needful to guide them in their conduct, or for any purpose that needs to be answered in this world. But nothing that appears to them in their neighbour can be sufficient to beget an absolute certainty concerning the state of his soul: for they see not his heart, nor can they see all his external behaviour.
