witnesses of these things and so is also the Holy Ghost whom God hath given to them that obey him,” Acts v. 32. The word witnesses to the ear, and the Spirit testifieth to our spirits, the truth and worth of that, and therefore the Spirit is a seal and a witness. The word is the Lord’s voice to his own children, bastards cannot know it, “but my sheep know my voice,” John x. 4, 16. You know no difference between the bleating of one sheep from another, but the poor lambs know their mother’s voice, there is a secret instinct of nature that is more powerful than many marks and signs, even so those who are begotten of God know his voice,—they discern that in it which all the world that hear it cannot discern—there is a sympathy between their souls and that living word. That word is the immortal seed they are begotten of and there is a natural instinct to love that, and to meditate in it, such an inclination to it, as in new born babes to the breasts, so the children of God do desire the sincere milk of the word, that they may grow thereby, as they were born of it, 1 Pet. ii. 2. In those scriptures which we read in your audience, you have something of their excellency, and our duty. There is a rich jewel in them, a precious pearl in that field, even Jesus Christ and in him eternal life; and therefore we ought to search the scriptures for this jewel, to dig in the field for this pearl, the doctrine of the prophets and apostles, as a sure foundation whereupon souls may build their eternal felicity, and the hope of it. Jesus Christ is the very chief stone in that foundation, whereupon the weight of all the saints and all their hope hangs. And therefore we ought to lean the weight of our souls only to this truth of God, and build our faith only upon it, and square our practice only by it.
