The Holy Spirit Bearing Witness to our Sonship.  
One of the most precious passages in the Bible regarding the work of the Holy Spirit is found in Rom. viii. 15, 16, R. V., “For ye received not the spirit of bondage again to fear; but ye received the spirit of adoption, whereby we cry Abba, Father. The Spirit Himself beareth witness with our spirit, that we are the children of God.” There are two witnesses to our sonship, first, our own spirit, taking God at His Word (“As many as received Him, to them gave He power to become the sons of God,” John i. 12), bears witness to our sonship. Our own spirit unhesitatingly affirms that what God says is true that we are sons of God because God says so. But there is another witness to our sonship, namely, the Holy Spirit. He bears witness together with our spirit. “Together with” is the force of the Greek used in this passage. It does not say that He bears witness to our spirit but “together with” it. How He does this is explained in Gal iv. 6, “Because ye are sons, God hath sent forth the Spirit of His Son into your hearts, crying, Abba, Father.” When we have received Jesus Christ as our Saviour and accepted God's testimony concerning Christ that through Him we have become sons, the [pg 137] Spirit of His Son comes into our hearts filling them with an overwhelming sense of sonship, and crying through our hearts, “Abba, Father.” The natural attitude of our hearts towards God is not that of sons. We may call Him Father with our lips, as when for example we repeat in a formal way, the prayer that Jesus taught us, “Our Father, which art in heaven,” but there is no real sense that He is our Father. Our calling Him so is mere words. We do not really trust Him. We do not love to come into His presence; we do not love to look up into His face with a sense of wonderful joy and trust because we are talking to our Father. We dread God. We come to Him in prayer because we think we ought to and perhaps we are afraid of what might happen if we did not. But when the Spirit of His Son bears witness together with our spirit to our sonship, then we are filled and thrilled with the sense that we are sons. We trust Him as we never even trusted our earthly Father. There is even less fear of Him than there was of our earthly father. Reverence there is, awe, but oh! such a sense of wonderful childlike trust.
 
Notice when it is that the Spirit bears witness with our spirit that we are the children of God. We have the order of experience in the order of the verses in Rom. viii. First we see the Holy Spirit setting us free from the law of sin and death, and consequently, the righteousness of the law fulfilled in us who walk not after the law but after the Spirit (vs. 2-4); then we have the believer not minding the things of the flesh but the things of the Spirit (v. 5); then we have the [pg 138] believer day by day through the Spirit putting to death the deeds of the body (v. 13); then we have the believer led by the Spirit of God; then and only then, we have the Spirit bearing witness to our sonship. There are many seeking the witness of the Spirit to their sonship in the wrong place. ............
