I find that Antinomians(161) confound this question, that they may have the more advantage in their darkness. The question is not concerning the grounds of a man’s believing in Christ, but concerning our assurance, or knowledge of our believing. There is a great mistake in Christians practice, in confounding these two. It makes Christians very unreasonable in their doubtings and exercises; therefore let us have this before our eyes,—faith, in its first and pure acting, is rather an adherence and cleaving of a lost soul to Christ, than an evidence of its interest in him, or of his everlasting love. You know all, that it is one thing to know a thing, or love a thing, and another thing to reflect upon it, and know that I know and love it. John did write to believers, that they might know they did believe, and believe yet more. These things then are both separable, and the one is posterior to the other,—“after that ye believed ye were sealed.” The persuasion of God’s love and our interest in Christ, is the Spirit’s seal set upon the soul. There is a mutual sealing here. The soul, by believing and trusting in Jesus Christ, “sets to its seal that God is true,” as John speaks, John iii. 33. When God speaks in his law, the soul receives that testimony of his justice and holiness, subscribes to the equity and righteousness of the sentence, by condemning itself. And when Christ speaks in the gospel, the soul seals that doctrine of free salvation, by approving and consenting with all its heart to the offer, subscribes to the way of salvation in Christ, and the truth of his promises. And thus is the truth of God and Christ sealed, by the soul’s believing. Then the Spirit of Jesus Christ afterward, when he pleaseth, irradiates and shines upon the soul, and discovers those things that are freely given, and witnesseth to the conscience of the believer, that he is a son of God. Thus the Spirit seals the believer, and gives his testimony to his truth.(162)
