_Direct._ XVII. Be very cautelous what conclusions you raise from any mere works of Providence. For the bold and blind exposition of these, hath led abundance into most heinous sins: no providence is instead of a law to us; but sometimes and ofttimes Providence changeth the matter of our duty, and so occasioneth the change of our obligations (as when the husband dieth, the wife is disobliged, &c.) But men of worldly dispositions do so over-value worldly things, that from them they venture to take the measure of God's love and hatred, and of the causes which he approveth or disapproveth in the world. And the wisdom of God doth seem on purpose, to cause such wonderful, unexpected mutations in the affairs of men, as shall shame the principles or spirits of these men, and manifest their giddiness and mutability to their confusion. One year they say, This is sure the cause of God, or else he would never own it as he doth; another year they say, If this had been God's cause he would never have so disowned it: just as the barbarians judged of Paul when the viper seized on his hand. And thus God is judged by them to own or disown by his prospering or afflicting, more than by his word. _Direct._ XVIII. In controversies which much depend on the sincerity or experience of godly men, take heed that you affect not singularity, and depart not from the common sense of the godly. For the workings of God's Spirit are better judged of by the ordinary tenor of them, than by some (real or supposed) case that is extraordinary. _Direct._ XIX. In controversies which most depend on the testimony of antiquity, depart not from the judgment of the ancients. They that stood within view of the days of the apostles could better tell what they did, and what a condition they left the churches in, than we can do. To appeal to the ancients in every cause, even in those where the later christians do excel them, is but to be fools in reverence of our forefathers' wisdom. But in points of history, or any thing in which they had the advantage of their posterity, their testimony is to be preferred.
