Our own convictions are ours because they are God's. Our own souls possess these emotions of love and tender desire going out to God--our own spirits possess them; but our own spirits did not originate them. They are ours by property; they are His by source. The spirit of a Christian man has no good thought in it, no true thought, no perception of the grace of God's Gospel, no holy desire, no pure resolution, which is not stamped with the sign of a higher origin, and is not the witness of God's Spirit in his spirit. The passage before us tells us that the sense of Fatherhood which is in the Christian's heart, and becomes his cry, comes from God's Spirit. This passage, and that in the Epistle to the Galatians which is almost parallel, put this truth very forcibly, when taken in connection. Ye have received,' says the text before us, the Spirit of adoption, whereby we cry, Abba, Father.' The variation in the Epistle to the Galatians is this: Because ye are sons, God hath sent forth the Spirit of His Son into your hearts, crying (the Spirit crying), Abba, Father.' So in the one text, the cry is regarded as the voice of the believing heart; and in the other the same cry is regarded as the voice of God's Spirit. And these two things are both true; the one would want its foundation if it were not for the other; the cry of the Spirit is nothing for me unless it be appropriated by me. I do not need to plunge here into metaphysical speculation of any sort, but simply to dwell upon the plain practical teaching of the Bible--a teaching verified, I believe, by every Christian's experience, if he will search into it--that everything in him which makes the Christian life, is not his, but is God's by origin, and his only by gift and inspiration. And the whole doctrine of my text is built on this one thought--without the Spirit of God in your heart, you never can recognise God as your Father. That in us which runs, with love, and childlike faith, and reverence, to the place where His honour dwelleth,' that in us which says Father,' is kindred with God, and is not the simple, unhelped, unsanctified human nature. There is no ascent of human desires above their source. And wherever in a heart there springs up heavenward a thought, a wish, a prayer, a trembling confidence, it is because that came down first from heaven, and rises to seek its level again. All that is divine in man comes from God. All that tends towards God in man is God's voice in the human heart; and were it not for the posses§ion and operation, the sanctifying and quickening, of a living divine Spirit granted to us, our souls would for ever cleave to the dust and dwell upon earth, nor ever rise to God and live in the light of His presence. Every Christian, then, may be sure of this, that howsoever feeble may be the thought and conviction in his heart of God's Fatherhood, he did not work it, he received it only, cherished it, thought of it, watched over it, was careful not to quench it; but in origin it was God's, and it is now and ever the voice of the Divine Spirit in the child's heart.
But, my friends, if this principle be true, it does not apply only to this one single attitude of the believing soul when it cries, Abba, Father; it must be widened out to comprehend the whole of a Christian's life, outward and inward, which is not sinful and darkened with actual transgression. To all the rest of his being, to everything in heart and life which is right and pure, the same truth applies. The Spirit itself beareth witness with our spirit' in every perception of God's word which is granted, in every revelation of His counsel which dawns upon our darkness, in every aspiration after Him which lifts us above the smoke and dust of this dim spot, in every holy resolution, in every thrill and throb of love and desire. Each of these is mine--inasmuch as in my heart it is experienced and transacted; it is mine, inasmuch as I am not a mere dead piece of matter, the passive recipient of a magical and supernatural grace; but it is God's; and therefore, and therefore only, has it come to be mine!
And if it be objected, that this opens a wide door to all manner of delusion, and that there is no more dangerous thing than for a man to confound his own thoughts with the operations of God's Spirit, let me just give you (following the context before us) the one guarantee and test which the Apostle lays down. He says, There is a witness from God in your spirits.' You may say, That witness, if it come in the form of these convictions in my own heart, I may mistake and falsely read. Well, then, here is an outward guarantee. As many as are led by the Spirit of God, they are the sons of God'; and so, on the regions both of heart and of life the consecrating thought,--God's work, and God's Spirit's work--is stamped. The heart with its love, the head with its understanding, the conscience with its quick response to the law of duty, the will with its resolutions,--these are all, as sanctified by Him, the witness of His Spirit; and the life with its strenuous obedience, with its struggles against sin and temptation, with its patient persistence in the quiet path of ordinary duty, as well as with the times when it rises into heroic stature of resignation or allegiance, the martyrdom of death and the martyrdom of life, this too is all (in so far as it is pure and right) the work of that same Spirit. The test of the inward conviction is the outward life; and they that have the witness of the Spirit within them have the light of their life lit by the Spirit of God, whereby they may read the handwriting on the heart, and be sure that it is God's and not their own.
