4. Another effect we have of his, Rom. viii. 16, “The Spirit itself beareth witness with our spirit, that we are the children of God.” You know whose children we are by nature, — children of Satan and of the curse, or of wrath. By the Spirit we are put into another capacity, and are adopted to be the children of God, inasmuch as by receiving the Spirit of our Father we become the children of our Father. Thence is he called, verse 15, “The Spirit of adoption.” Now, sometimes the soul, because it hath somewhat remaining in it of the principle that it had in its old condition, is put to question whether it be a child of God or no; and thereupon, as in a thing of the greatest importance, puts in its claim, with all the evidences that it hath to make good its title. The Spirit comes and bears witness in this case. An allusion it is to judicial proceedings in point of titles and evidences. The judge being set, the person concerned lays his claim, produceth his evidences, and pleads them; his adversaries endeavouring all that in them lies to invalidate them, and disannul his plea, and to cast him in his claim. In the midst of the trial, a person of known and approved integrity comes into the court, and gives testimony fully and directly on the behalf of the claimer; which stops the mouths of all his adversaries, and fills the man that pleaded with joy and satisfaction. So is it in this case. The soul, by the power of its own conscience, is brought before the law of God. There a man puts in his plea, — that he is a child of God, that he belongs to God’s family; and for this end produceth all his evidences, every thing whereby faith gives him an interest in God. Satan, in the meantime, opposeth with all his might; sin and law assist him; many flaws are found in his evidences; the truth of them all is questioned; and the soul hangs in suspense as to the issue. In the midst of the plea and contest the Comforter comes, and, by a word of promise or otherwise, overpowers the heart with a comfortable persuasion (and bears down all objections) that his plea is good, and that he is a child of God. And therefore it is said of him, Συμμαρτυρεῖ τῷ Πνεύματι ἡμῶν. When our spirits are pleading their right and title, he comes in and bears witness on our side; at the same time enabling us to put forth acts of filial obedience, kind and childlike; which is called “crying, Abba, Father,” Gal. iv. 6. Remember still the manner of the Spirit’s working, before mentioned, — that he doth it effectually, voluntarily, and freely. Hence sometimes the dispute hangs long, — the cause is pleading many years. The law seems sometimes to prevail, sin and Satan to rejoice; and the poor soul is filled with dread about its inheritance. Perhaps its own witness, from its faith, sanctification, former experience, keeps up the plea with some life and comfort; but the work is not done, the conquest is not fully obtained, until the Spirit, who worketh freely and effectually, when and how he will, comes in with his testimony also; clothing his power with a word of promise, he makes all parties concerned to attend unto him, and puts an end to the controversy.
