A work is not to be judged by any effects on the bodies of men; such as tears, trembling, groans, loud outcries, agonies of body, or the failing of bodily strength. The influence persons are under is not to be judged of one way or other by such effects on the body. Scripture nowhere gives us any such rule. We cannot conclude that persons are under the influence of the true Spirit because we see such effects upon their bodies. This is not given as a mark of the true Spirit; nor on the other hand, have we any reason to conclude from any such outward appearances that persons are not under the influence of the Spirit of God. There is no rule of Scripture given us by which to judge spirits that either expressly or indirectly excludes such effects on the body, nor does reason exclude them.
Jonathan Edwards
