Before I come to the common directions for the exercise of grace, and walking with God, containing the common duties of christianity, I shall lay down some previous instructions, proper to those that are but newly entered into religion (presupposing what is said in my book of directions to those that are yet under the work of conversion, to prevent their miscarrying by a false superficial change).
_Direct._ I. Take heed lest it be the novelty or reputation of truth and godliness, that takes with you, more than the solid evidence of their excellency and necessity; lest when the novelty and reputation are gone, your religion wither and consume away.
It is said of John and the Jews by Christ, "He was a burning and a shining light, and ye were willing for a season to rejoice in his light," John v. 35. All men are affected most with things that seem new and strange to them. It is not only the infirmity of children, that are pleased with new clothes, and new toys and games; but even to graver, wiser persons, new things are most affecting, and commonness and custom dulls delight. Our habitations, and possessions, and honours, are most pleasing to us at the first; and every condition of life doth most affect us at the first: if nature were not much for novelty, the publishing of news-books would not have been so gainful a trade so long, unless the matter had been truer and more desirable. Hence it is that changes are so welcome to the world, though they prove ordinarily to their cost. No wonder then, if religion be the more acceptable, when it comes with this advantage. When men first hear the doctrine of godliness, and the tidings of another world, by a powerful preacher opened and set home, no wonder if things of so great moment affect them for a time: it is said of them that received the seed of God's word as into stony ground, that "forthwith it sprung up," and they "anon with joy received it," Matt. xiii. 5, 20; but it quickly withered for want of rooting. These kind of hearers can no more delight still in one preacher, or one profession, or way, than a glutton in one dish, or an adulterer in one harlot: for it is but a kind of sensual or natural pleasure that they have in the highest truths; and all such delight must be fed with novelty and variety of objects. The Athenians were inquisitive after Paul's doctrine as novelty, though after they rejected it, as seeming to them incredible: Acts xvii. 19-21, "May we know what this new doctrine whereof thou speakest is? For thou bringest certain strange things to our ears: we would know therefore what these things mean. For all the Athenians and strangers which were there, spent their time in nothing else, but to tell or hear some new thing."
To this kind of professors, the greatest truths grow out of fashion, and they grow weary of them, as of dull and ordinary things: they must have some new light, or new way of religion that lately came in fashion: their souls are weary of that manna that at first was acceptable to them, as angels' food. Old things seem low, and new things high to them; and to entertain some novelty in religion, is to grow up to more maturity: and too many such at last so far overthrive their old apparel, that the old Christ and old gospel are left behind them.
