Terror of Conscience For Sin is preferable to False Security or Presumption

It is fit that professors of all sorts should be reminded of these things; for we may see not a few of them under visible decays, without any sincere endeavours after a recovery, who yet please themselves that the root of the matter is in them. It is so, if love of the world, conformity unto it, negligence in holy duties, and coldness in spiritual love, be an evidence of such decays. but let none deceive their own souls; wherever there is a saving principle of grace, it will be thriving and growing unto the end. And if it falls under obstructions, and thereby into decays for a season, it will give no rest or quietness unto the soul, wherein it is, but will labour continually for a recovery. Peace in a spiritually decaying condition is a soul ruining security; better be under terror on the account of surprisal into some sin, than be in peace under evident decays of spiritual life.
