THE SPIRIT ITSELF BEARETH WITNESS with our spirit,
that WE ARE THE CHILDREN OF GOD.
–Romans 8:16–

Did not our HEART BURN WITHIN us while He talked with us on the road,
and while He opened THE SCRIPTURES to us?
–Luke 24:32 (NKJV)–

I was mute with silence,
I held my peace even from good;
And my sorrow was stirred up.
MY HEART WAS HOT WITHIN ME;
While I was musing, THE FIRE BURNED.
Then I spoke with my tongue.
–Psalm 39:2-3 (NKJV)–

I said, “I will not make mention of Him,
Nor speak anymore in His name.”
BUT HIS WORD WAS IN MY HEART LIKE A BURNING FIRE
Shut up in my bones;
I was weary of holding it back,
And I could not.
–Jeremiah 20:9 (NKJV)–

HE WILL BAPTIZE YOU WITH THE HOLY SPIRIT AND FIRE.
–Matthew 3:11 (NKJV)–

There appeared to them divided tongues,
AS OF FIRE, and one sat upon each of them.
–Acts 2:3 (NKJV)–

I know your works, that you are neither cold nor hot. I COULD WISH YOU WERE cold or HOT. So then, because you are lukewarm, and neither cold nor HOT, I will vomit you out of My mouth.
–Revelation 3:15-16 (NKJV)–

With the spirit of every true believer, by A TESTIMONY DISTINCT FROM that of his own spirit, or the testimony of a good conscience. Happy they who enjoy this CLEAR AND CONSTANT.
—Wesley’s Explanatory Notes, Romans 8:16–

That same Spirit, the Spirit of adoption; that is, the Spirit who witnesses this adoption; which can be no other than the Holy Ghost himself, and certainly cannot mean any disposition or affection of mind which the adopted person may feel; for such a disposition must arise from a knowledge of this adoption, and the knowledge of this adoption cannot be given by any human or earthly means; it must come from God himself: therefore the αυτοτοπνευμα must have reference to that Spirit, by whom alone the knowledge of the adoption is witnessed to the soul of the believer…In our understanding, the place or recipient of light and information; and the place or faculty to which such information can properly be brought. This is done that we may have the highest possible evidence of the work which God has wrought. As the window is the proper medium to let the light of the sun into our apartments, so the understanding is the proper medium of conveying the Spirit’s influence to the soul. We, therefore, have the utmost evidence of the fact of our adoption which we can possibly have; we have the Word and Spirit of God; and the Word sealed on our spirit by the Spirit of God. And this is not a momentary influx: if we take care to walk with God, and not grieve the Holy Spirit, we shall have an abiding testimony; and while we continue faithful to our adopting Father, the Spirit that witnesses that adoption will continue to witness it; and hereby we shall know that we are of God by the Spirit which he giveth us.
—The Adam Clarke Commentary, Romans 8:16–

In the evening I went very unwillingly to a society in Aldersgate Street, where one was reading Luther’s preface to the Epistle to the Romans. About a quarter before nine, while he was describing the change which God works in the heart through faith in Christ, I felt my heart strangely warmed. I felt I did trust in Christ, Christ alone, for salvation; and an assurance was given me that He had taken away my sins, even mine, and saved me from the law of sin and death.
–John Wesley–

The inward witness, son, the inward witness,
that is the proof, the strongest proof, of Christianity.
–Samuel Wesley–

1. The sum of all this is: The testimony of the Spirit is an inward impression on the souls of believers, whereby the Spirit of God directly testifies to their spirit, that they are children of God. And it is not questioned, whether there is a testimony of the Spirit; but whether there is an direct testimony; whether there is any other than that which arises from a consciousness of the fruit of the Spirit. We believe there is; because this is the plain natural meaning of the text, illustrated both by the preceding words, and by the parallel passage in the Epistle to the Galatians; because, in the nature of the thing, the testimony must precede the fruit which springs from it and because this plain meaning of the word of God is confirmed by the experience of innumerable children of God; yea, and by the experience of all who are convinced of sin, who can never rest till they have a direct witness; and even of the children of the world, who, not having the witness in themselves, one and all declare, none can know his sins forgiven.

2. And whereas it is objected, that experience is not sufficient to prove a doctrine unsupported by Scripture; — that madmen and enthusiasts of every kind have imagined such a witness that the design of that witness is to prove our profession genuine, which design it does not answer; — that the Scripture says, “The tree is known by its fruit;” “examine yourselves; prove your ownselves;” and, meantime, the direct witness is never referred to in all the Book of God; — that it does not secure us from the greatest delusions; and, Lastly, that the change wrought in us is a sufficient testimony, unless in such trials as Christ alone suffered: — We answer, 1. Experience is sufficient to confirm a doctrine which is grounded on Scripture. 2. Though many fancy they experience what they do not, this is no prejudice to real experience. 3. The design of that witness is, to assure us we are children of God; and this design it does answer. 4. The true witness of the Spirit is known by its fruit, “love, peace, joy;” not indeed preceding, but following it. 5. It cannot be proved, that the direct as well as the indirect witness is not referred to in that very text, “Know ye not your ownselves, that Jesus Christ is in you.” 6. The Spirit of God, witnessing with our spirit, does secure us from all delusion: And, Lastly, we are all liable to trials, wherein the testimony of our own spirit is not sufficient; wherein nothing less than the direct testimony of God’s Spirit can assure us that we are his children.

3. Two inferences may be drawn from the whole: The First, let none ever presume to rest in any supposed testimony of the Spirit which is separate from the fruit of it. If the Spirit of God does really testify that we are the children of God, the immediate consequence will be the fruit of the Spirit, even “love, joy, peace, long-suffering, gentleness, goodness, fidelity, meekness, temperance.” And however this fruit may be clouded for a while, during the time of strong temptation, so that it does not appear to the tempted person, while Satan is sifting him as wheat; yet the substantial part of it remains, even under the thickest cloud. It is true, joy in the Holy Ghost may be withdrawn, during the hour of trial; yea, the soul may be “exceeding sorrowful,” while “the hour and power of darkness” continue; but even this is generally restored with increase, till we rejoice “with joy unspeakable and full of glory.”

4. The Second inference, is, let none rest in any supposed fruit of the Spirit without the witness. There may be foretastes of the Spirit without the witness. There may be foretastes of joy, of peace, of love, and those not delusive, but really from God, long before we have the witness in ourselves; before the Spirit of God witnesses with our spirits that we have “redemption in the blood of Jesus, even the forgiveness of sins.” Yea, there may be a degree of long-suffering, of gentleness, of fidelity, meekness, temperance, (not a shadow thereof, but a real degree, by the preventing grace of God,) before we “are accepted in the Beloved,” and, consequently, before we have a testimony of our acceptance: But it is by no means advisable to rest here; it is at the peril of our souls if we do. If we are wise, we shall be continually crying to God, until his Spirit cry in our heart, “Abba, Father!” This is the privilege of all the children of God, and without this we can never be assured that we are his children. Without this we cannot retain a steady peace, nor avoid perplexing doubts and fears. But when we have once received this Spirit of adoption, this “peace which passeth all understanding,” and which expels all painful doubt and fear, will “keep our hearts and minds in Christ Jesus.” And when this has brought forth its genuine fruit, all inward and outward holiness, it is undoubtedly the will of Him that calleth us, to give us always what he has once given; so that there is no need that we should ever more be deprived of either the testimony of God’s Spirit, or the testimony of our own, the consciousness of our walking in all righteousness and true holiness.
