Mark the terms of the passage: The Spirit itself beareth witness with our spirit.' It is not so much a revelation made to my spirit, considered as the recipient of the testimony, as a revelation made in or with my spirit considered as co-operating in the testimony. It is not that my spirit says one thing, bears witness that I am a child of God; and that the Spirit of God comes in by a distinguishable process, with a separate evidence, to say Amen to my persuasion; but it is that there is one testimony which has a conjoint origin--the origin from the Spirit of God as true source, and the origin from my own soul as recipient and co-operant in that testimony. From the teaching of this passage, or from any of the language which Scripture uses with regard to the inner witness, it is not to be inferred that there will rise up in a Christian's heart, from some origin consciously beyond the sphere of his own nature, a voice with which he has nothing to do; which at once, by its own character, by something peculiar and distinguishable about it, by something strange in its nature, or out of the ordinary course of human thinking, shall certify itself to be not his voice at all, but Goofs voice. That is not the direction in which you are to look for the witness of God's Spirit. It is evidence borne, indeed, by the Spirit of God; but it is evidence borne not only to our spirit, but through it, with it. The testimony is one, the testimony of a man's own emotion, and own conviction, and own desire, the cry, Abba, Father! So far, then, as the form of the evidence goes, you are not to look for it in anything ecstatic, arbitrary, parted off from your own experience by a broad line of demarcation; but you are to look into the experience which at first sight you would claim most exclusively for your own, and to try and find out whether there there be not working with your soul,working through it, working beneath it, distinct from it but not distinguishable from it by anything but its consequences and its fruit-fulness--a deeper voice than yours--a' still small voice,' --no whirlwind, nor fire, nor earthquake--but the voice of God speaking in secret, taking the voice and tones of your own heart and your own consciousness, and saying to you, Thou art my child, inasmuch as, operated by My grace, and Mine inspiration alone, there rises, tremblingly but truly, in thine own soul the cry, Abba, Father.'
So much, then, for the form of this evidence--my own conviction. Then with regard to the substance of it: conviction of what? The text itself does not tell us what is the evidence which the Spirit bears, and by reason of which we have a right to conclude that we are the children of God. The previous verse tells us. I have partially anticipated what I have to say on that point, but it will bear a little further expansion. Ye have not received the spirit of bondage again to fear; but ye have received the Spirit of adoption, whereby we cry Abba, Father.' The Spirit itself,' by this means of our cry, Abba, Father, beareth witness with our spirit, that we are the children of God.' The substance, then, of the conviction which is lodged in the human spirit by the testimony of the Spirit of God is not primarily directed to our relation or feelings to God, but to a far grander thing than that--to God's feelings and relation to us. Now I want you to think for one moment, before I pass on, how entirely different the whole aspect of this witness of the Spirit of which Christian men speak so much, and sometimes with so little understanding, becomes according as you regard it mistakenly as being the direct testimony to you that you are a child of God, or rightly as being the direct testimony to you that God is your Father. The two things seem to be the same, but they are not. In the one case, the false case, the mistaken interpretation, we are left to this, that a man has no deeper certainty of his condition, no better foundation for his hope, than what is to be drawn from the presence or absence of certain emotions within his own heart. In the other case, we are admitted into this wide place,' that all which is our own is second and not first, and that the true basis of all our confidence lies not in the thought of what we are and feel to God, but in the thought of what God is and feels to us. And instead, therefore, of being left to labour for ourselves, painfully to search amongst the dust and rubbish of our own hearts, we are taught to sweep away all that crumbled, rotten surface, and to go down to the living rock that lies beneath it; we are taught to say, in the words of the book of Isaiah, Doubtless Thou art our Father--we are all an unclean thing; our iniquities, like the wind, have carried us away'; there is nothing stable in us; our own resolutions, they are swept away like the chaff of the summer threshing-floor, by the first gust of temptation; but what of that?--in those is continuance, and we shall be saved!' Ah, brethren! expand this thought of the conviction that God is my Father, as being the basis of all my confidence that I am His child, into its widest and grandest form, and it leads us up to the blessed old conviction, I am nothing, my holiness is nothing, my resolutions are nothing, my faith is nothing, my energies are nothing; I stand stripped, and barren, and naked of everything, and I fling myself out of myself into the merciful arms of my Father in heaven! There is all the difference in the world between searching for evidence of my sonship, and seeking to get the conviction of God's Fatherhood. The one is an endless, profitless, self-tormenting task; the other is the light and liberty, the glorious liberty, of the children of God.
And so the substance of the Spirit's evidence is the direct conviction based on the revelation of God's infinite love and fatherhood in Christ the Son, that God is my Father; from which direct conviction I come to the conclusion, the inference, the second thought, Then I may trust that I am His son. But why? Because of anything in me? No: because of Him. The very emblem of fatherhood and sonship might teach us that that depends upon the Father's will and the Father's heart. The Spirit's testimony has for form my own conviction: and for substance my humble cry,' Oh Thou, my Father in heaven!' Brethren, is not that a far truer and nobler kind of thing to preach than saying, Look into your own heart for strange, extraordinary, distinguishable signs which shall mark you out as God's child--and which are proved to be His Spirit's, because they are separated from the ordinary human consciousness? Is it not far more blessed for us, and more honouring to Him who works the sign, when we say, that it is to be found in no out-of-rule, miraculous evidence, but in the natural (which is in reality supernatural) working of His Spirit in the heart which is its recipient, breeding there the conviction that God is my Father? And oh, if I am speaking to any to whom that text, with all its light and glory, has seemed to lift them up into an atmosphere too rare and a height too lofty for their heavy wings and unused feet, if I am speaking to any Christian man to whom this word has been like the cherubim and flaming sword, bright and beautiful, but threatening and repellent when it speaks of a Spirit that bears witness with our spirit--I ask you simply to take the passage for yourself, and carefully and patiently to examine it, and see if it be not true what I have been saying, that your trembling con-viction-sister and akin as it is to your deepest distrust and sharpest sense of sin and unworthiness--that your trembling conviction of a love mightier than your own, everlasting and all-faithful, is indeed the selectest sign that God can give you that you are His child. Oh, brethren and sisters! be confident; for it is not false confidence: be confident if up from the depths of that dark well of your own sinful heart there rises sometimes, through all the bitter waters, unpolluted and separate, a sweet conviction, forcing itself upward, that God hath love in His heart, and that God is my Father. Be confident; the Spirit itself beareth witness with your spirit.'
