It is a matter, therefore, of great importance, my dear hearers, to know whether we may speak peace to our hearts. We are all desirous of peace; peace is an unspeakable blessing; how can we live without peace? And, therefore, people from time to time must be taught how far they must go and what must be wrought in them before they can speak peace to their hearts. This is what I design at present, that I may deliver my soul, that I may be free from the blood of all those to whom I preach--that I may not fail to declare the whole counsel of God. I shall, from the words of the text, endeavor to show you what you must undergo and what must be wrought in you before you can speak peace to your hearts. But before I come directly to this give me leave to premise a caution or two. And the first is, that I take it for granted you believe religion to be an inward thing; you believe it to be a work of the heart, a work wrought in the soul by the power of the Spirit of God. If you do not believe this, you do not believe your Bibles. If you do not believe this, tho you have got your Bibles in your hand, you hate the Lord Jesus Christ in your heart; for religion is everywhere represented in Scripture as the work of God in the heart. "The kingdom of God is within us," says our Lord; and, "he is not a Christian who is one outwardly; but he is a Christian who is one inwardly." If any of you place religion in outward things, I shall not perhaps please you this morning; you will understand me no more when I speak of the work of God upon a poor sinner's heart than if I were talking in an unknown tongue. I would further premise a caution, that I would by no means confine God to one way of acting. I would by no means say that all persons, before they come to have a settled peace in their hearts, are obliged to undergo the same degrees of conviction. No; God has various ways of bringing His children home; His sacred Spirit bloweth when, and where, and how it listeth. But, however, I will venture to affirm this: that before ever you can speak peace to your heart, whether by shorter or longer continuance of your convictions, whether in a more pungent or in a more; gentle way, you must undergo what I shall hereafter lay down in the following discourse. First, then, before you can speak peace to your hearts, you must be made to see, made to feel, made to weep over, made to bewail, your actual transgressions against the law of God. According to the covenant of works, "the soul that sinneth it shall die"; curst is that man, be he what he may, be he who he may, that continueth not in all things that are written in the book of the law to do them.
