The Inward Witness to Christianity

By Isaac Watts

THERE are two points of great and solemn importance, which it becomes every man to enquire into: First, Whether the religion he professes be true and divine; and then, Whether he has so far complied with the rules of this religion, as to stand entitled to the blessings thereof.

The christians of our age and nation, have been nursed up amongst the forms of christianity from their childhood; they take it for granted their religion is divine and true, and therefore seldom enter into the first enquiry: but when they come to think in good earnest about religious affairs, their great concern is with the second, viz. to know whether they have so far complied with the rules of the gospel of Christ, as to obtain an interest in the promised blessings of it. And when they hear such a text as this, He that believeth, hath the witness in himself, they immediately expect that the meaning and design of it should be to witness the truth of their own faith, and consequently to prove their own title to salvation.

I. The Inward Witness to Christianity

1 John 5: 10—He that believeth on the Son of God, hath the Witness in himself.

The First Part

THERE are two points of great and solemn importance, which it becomes every man to enquire into: First, Whether the religion he professes be true and divine; and then, Whether he has so far complied with the rules of this religion, as to stand entitled to the blessings thereof.

The christians of our age and nation, have been nursed up amongst the forms of christianity from their childhood; they take it for granted their religion is divine and true, and therefore seldom enter into the first enquiry: but when they come to think in good earnest about religious affairs, their great concern is with the second, viz. to know whether they have so far complied with the rules of the gospel of Christ, as to obtain an interest in the promised blessings of it. And when they hear such a text as this, He that believeth, hath the witness in himself, they immediately expect that the meaning and design of it should be to witness the truth of their own faith, and consequently to prove their own title to salvation.

But in the first christian age the case was far otherwise. The gospel itself was not then universally established, and the disciples of this new religion might have frequent doubts in their own minds concerning the truth of it, while they saw it disallowed and opposed by the world round about them. It was evidently necessary therefore for them to enquire, whether it came from God or no? And it is with this view the apostle John writes these words, He that believeth on the Son of God hath the witness in himself; viz. he hath a proof within himself that eternal life is in the Son, ver. 11 and is to be obtained by our believing in him. It is to the truth of this doctrine that the three bear record in heaven, the Father, the Word, and the Holy Ghost; and the three on earth, the spirit, and the water, and the blood. And though the proof of the sincerity and truth of our faith now may be derived from hence by a further consequence, yet the first and direct design of the apostle is to shew, that the truth and divinity of our religion has an inward witness to it in the heart of every believer.

Here give me leave to put you in mind, that it is necessary for you, as it was for the primitive christians, to settle your profession of christianity upon solid grounds; otherwise you are christians but for the same reason that makes a Turk a disciple of Mahomet, or a heathen a worshipper of the Gods of his country; that is, because you were born in such a climate, and under such a meridian. And can you be contented with so poor a pretence to the noblest religion? and lay so sandy a foundation for your eternal hopes? Besides, the day in which we live, threatens you with bold temptations; and how will you stand if you have no surer grounds? Infidelity is a growing weed; the contempt and ridicule of revealed religion, flourish and become fashionable among the gay part of the world; and if you are not furnished with some solid proofs of the gospel of Christ, you may be in great danger of losing your faith; you may be tempted to yield up your religion to a witty jest, and become a heathen for company.

I might say another thing to awaken you to acquaint yourselves with some arguments that will justify and support your belief of the gospel. Suppose you think you have complied with the rules of your religion, and have raised your hopes of heaven to a high degree; should Satan the tempter spread his darkness round your souls, and in a melancholy and gloomy hour assault your faith with such bold questions as these, How do you know that christianity is the true religion? What tokens have you to shew that it came from God? If you have no other answer to make, but that it is the religion of your country, that you are born and bred up in it, think with yourselves how your spirits will be surprized, your comforts languish, and all your high built hopes totter to the ground; unless the Spirit of God, by his uncommon and sovereign grace, should give in an answer to the temptation, and by some immediate and convincing argument support your faith: but if you are negligent to lay a good foundation at first, you have no reason to expect such a divine favour.

Let the importance of this concern therefore keep your attention awake, while I briefly run over some of the proofs of christianity, and thus lead you down to the surest and best of them, which is contained in my text.

Many are the outward testimonies which God hath given to the gospel of his Son; many witnesses have confirmed it from the time that Christ appeared in the flesh, to the day when St. John wrote this epistle. If we trace his life from the cradle in the manger to his cross and the grave, we shall find the rays of divinity still shining round his doctrine and his works, still pointing to his person, and proving his commission with a convincing and resistless light. At his birth the witnessing angels appeared in much brightness, and while the Son of God lay an infant below, his record was on high; for there appeared a strange new star, and was his witness in heaven. The wise men of the East were his witnesses, when they came from afar, and paid tributes and offerings, gold and incense to the God, the king of Israel. Simeon and Anna in the temple, by the Spirit of prophecy witnessed to the holy child Jesus. And the doctors with whom he disputed at twelve years old, were his witnesses that there was something in him more than man. At his baptism the Father and the Spirit witnessed to the Son of God; they told the world that this was He, the Messiah: The Father by a voice from heaven, saying, This is my beloved Son in whom I am well pleased; and the Spirit descending upon him like a dove. His life was a life of wonders, and each of them witnessed to the truth of his commission, and to the divinity of his doctrine. Every blind eye that he opened, saw and witnessed Jesus, and declared his divine power. Every one of the dead that he raised were his witnesses. They came from the land of silence to speak his glory, and to give a loud testimony to his mission from heaven. The devils themselves, when he drove them out of their possessions, confessed that he was Christ, The holy one of God; but he had no mind to accept their witness, and therefore forbade them to speak. Miracles attended him to the cross and the grave, and opened the grave again for him, and made a passage for him to his Father’s right hand. Nor did the witnesses of his person and of his doctrine then cease; for that salvation which began to be spoken by Jesus the Lord, was afterwards published by those that heard him, God himself bearing them witness with signs and wonders; as in Heb. 2: 3, 4.

But all these still were outward witnesses to convince an unbelieving world. There is an inward witness that my text speaks of, that belongs to every true christian: He that
