II. It is a witness that will, in some measure, appear in the life, wheresoever it is written in the heart: For eternal life is an active principle, it will be discovering and exercising itself. Is it possible, that a man should have the pardon of his sins, and sweet peace of conscience, a sense of the love of God, who is an infinite good, a joyful satisfaction in his heavenly favour, and manifest nothing of this in his aspect and behaviour? That he should shew no serenity of countenance, no sweetness of temper, no inward joy; Is it possible that he should have an utter aversion to sin, a hatred of all iniquity in his heart, and not make it appear in his life? That he should maintain a holy contempt of this world, and scorn of it, in comparison of the future glories that his eye is fixed upon, so warm a zeal for God, and so hearty a love to men, and not manifest it to the world? Surely his life will be above, where his heart is; and his heart will be in heaven, where his treasures are. _Our conversation is in heaven, says the blessed Paul, under the influence of this religion and these hopes_; Phil. iii. 20, 21. It is true indeed, this is a testimony that cannot be communicated to others, in the same measure and manner that it is felt by the persons that believe. In this respect it is like the hidden manna, which none knows but that they taste of it; yet those that feed upon it daily, will discover it in some outward appearances; as you read of Jonathan, in the day when he was faint in pursuing his enemies, he tasted of the honey, and his eyes were enlightened; 1 Sam. xiv. 27. Just so will it be with the soul that hath tasted of the gospel of Christ, this food of eternal life; he will discover it in his language, in his behaviour; and it is a shame to those that profess to be believers, that in all things they look so much like the men of this world, and do not discover it in their lives, and witness what they have in their hearts, even the beginning of eternal life: If we are the epistle of Christ, we shall be, in some measure, known and read of all men; 2 Cor. iii. 2, 3. Christianity in the soul, eternal life begun in the heart, will be like the sweet ointment of the right-hand, that bewrays itself, and cannot be hid; Prov. xxvii. 16. Ye christians, ye are the light of the earth, ye believers are the salt of the world; ye must not appear like others if you would be like yourselves; the honour of God your Saviour demands some sensible and important difference. Ye must not be too much like the world, if ye mean to give glory or evidence to the religion of Christ; John xv. 19. Rom. xii. 2.
