VI. I shall, therefore, in the next place, to bring all things nearer home, inquire, "What is the nature of that repentance and reformation which at this time God requires of us all, that we may not perish in his sore displeasure?" After a devastation made of the treasure of the Roman empire by sundry tyrants successively, Vespasian coming to the government, acquainted the senate that there was need of so many millions of money, that the empire might stand; -- not that it might flourish and grow vigorous, whereunto much more was required, but that it might be preserved from dissolution and ruin. And I shall propose, not what is requisite to render the church of God in this nation orderly, beautiful, and vigorous, but only what is necessary that it may stand and live, by a deliverance from desolating judgments. And, -- First. The repentance which, in any case, God requireth absolutely, is that which is internal and real, in sincere conversion unto himself, accompanied with fruits meet for such repentance. So is it declared, Ezek. xviii. 30, 31, "Therefore I will judge you, O house of Israel, every one according to his ways, saith the Lord God. Repent, and turn yourselves from all your transgressions; so iniquity shall not be your ruin. Cast away from you all your transgressions, whereby ye have transgressed; and make you a new heart and a new spirit, for why will ye die, O house of Israel?" A new heart and a new spirit, or real internal conversion unto God, by the grace of the covenant, is required in this repentance, as the renunciation and relinquishment of all iniquities must be the fruit of it. So also is it expressed, Isa. i. 16, 17.
