A wide difference
I answer, the holy Scriptures abound with marks by which the one may be distinguished from the other. They describe, in the plainest manner, the circumstances which go before, which accompany, and which follow the true, genuine testimony of the Spirit of God with the spirit of a believer. Whoever carefully weighs and attends to these will not need to put darkness for light. He will perceive so wide a difference, with respect to all these, between the real and the pretended witness of the Spirit, that there will be no danger, I might say no possibility, of confounding the one with the other.

3. I answer, the holy scriptures abound with marks, whereby the one may be distinguished from the other. They describe in the plainest manner the circumstances which go before, which accompany, and which follow, the true, genuine testimony of the Spirit of God with the spirit of a believer. Whoever carefully weighs and attends to these, will not need to put darkness for light. He will perceive so wide a difference with respect to all these, between the real and the pretended witness of the Spirit, that there will be no danger, I might say, no possibility, of confounding the one with the other.
