We are of God - John here, doubtless, refers to himself, and to those who taught the same doctrines which he did. He takes it for granted that those to whom he wrote would admit this, and argues from it as an indisputable truth. He had given them such evidence of this, as to establish his character and claims beyond a doubt; and he often refers to the fact that he was what he claimed to be, as a point which was so well established that no one would call it in question. See John 19:35; John 21:24; 3 John 1:12. Paul, also, not unfrequently refers to the same thing respecting himself; to the fact - a fact which no one would presume to call in question, and which might be regarded as the basis of an argument - that he and his fellow apostles were what they claimed to be. See 1 Corinthians 15:14-15; 1 Thessalonians 2:1-11. Might not, and ought not, all Christians, and all Christian ministers, so to live that the same thing might be assumed in regard to them in their contact with their fellow-men; that their characters for integrity and purity might be so clear that no one would be disposed to call them in question? There are such men in the church and in the ministry now; why might not all be such?

He that knoweth God, heareth us - Every one that has a true acquaintance with the character of God will receive our doctrine. John might assume this, for it was not doubted, he presumed, that he was an apostle and a good man; and if this were admitted, it would follow that those who feared and loved God would receive what he taught.

Hereby - By this; to wit, by the manner in which they receive the doctrines which we have taught.

Know we the spirit of truth, and the spirit of error - We can distinguish those who embrace the truth from those who do not. Whatever pretensions they might set up for piety, it was clear that if they did not embrace the doctrines taught by the true apostles of God, they could not be regarded as his friends; that is, as true Christians. It may be added that the same test is applicable now. They who do not receive the plain doctrines laid down in the word of God, whatever pretensions they may make to piety, or whatever zeal they may evince in the cause which they have espoused, can have no well-founded claims to the name Christian. One of the clearest evidences of true piety is a readiness to receive all that God has taught. Compare Matthew 18:1-3; Mark 10:15; James 1:19-21.

We are of God - We, apostles, have the Spirit of God, and speak and teach by that Spirit. He that knoweth God - who has a truly spiritual discernment, heareth us - acknowledges that our doctrine is from God; that it is spiritual, and leads from earth to heaven.

Hereby know we the Spirit of truth - The doctrine and teacher most prized and followed by worldly men, and by the gay, giddy, and garish multitude, are not from God; they savor of the flesh, lay on no restraints, prescribe no cross-bearing, and leave every one in full possession of his heart's lusts and easily besetting sins. And by this, false doctrine and false teachers are easily discerned.

We are of God,.... Not only as the chosen of God, the children of God, regenerated ones, and believers, but as ministers of the Gospel; they were chosen, and called, and sent of God to preach the Gospel, and were qualified for it, by gifts received from him, and had their doctrine from him, as well as their commission and mission: they were not of the world, and therefore did not speak of the world, nor things suited to worldly men; but being of God, they spoke the words of God, which were agreeable to him, which made for the glory of the three divine Persons, and were consistent with the divine perfections; which maintained the honour and dignity of the persons in the Godhead; which magnified the grace of God in salvation, and debased the creature:

he that knoweth God; not only as the God of nature and providence, but as in Christ, and that not only professionally, but practically; that has an experimental knowledge of him, that knows him as exercising lovingkindness, having tasted of his grace and goodness; that knows him so as to trust in him, and love him; for such a knowledge of God is meant, as has true real affection to him joined with it; so that it is he that loves his name, his glory, his truths, and his ordinances: he

heareth us: not only externally, constantly attending on the ministry of the word, as such do; but internally, understanding what is heard, receiving it in love, cordially embracing it, and firmly believing it, and acting according to it:

he that is not of God; who is not born of God, but is as he was when born into the world, and is of it: and who does not righteousness, nor loves his brother, nor confesses the divinity, humanity, and offices of Christ, and so is not on the side of truth, nor has the truth of grace in him; see 1 John 3:10; such a man

heareth not us; he is a mere natural man, a carnal and unregenerate man; and such an one cannot attend on a Gospel ministry, or receive Gospel doctrines, which are with him senseless, stupid, and foolish notions, yea, foolishness itself; nor can he know and understand them through ignorance, and want, of a spiritual discerning; they are hard sayings, and he cannot hear, nor bear them; and when this is the case, it is a plain token of unregeneracy, and that such persons are not of God; see John 8:47.

Hereby know we the spirit of truth, and the spirit of error; the difference between truth and error; can distinguish one from another, and discern who are the true ministers of Christ, and who are the false teachers; for not only the word of God, the Scriptures of truth, are the test and standard, the touchstone to bring them to, and try them by; and the doctrines they severally bring show who they are; but even their very hearers distinguish them. Spirits, or men pretending to the Spirit of God, may be known in a great measure by their followers; they who have the spirit of error, and are of the world, they are followed, and caressed, and applauded by the men of the world, by unregenerate persons; they who have the spirit of truth, and are of God, they are heard and approved of, and embraced by spiritual men, by such who know God in Christ, and have tasted that the Lord is gracious.

He that knoweth (ὁ γινώσκων)

Lit., the one knowing: he who is habitually and ever more clearly perceiving and recognizing God as his Christian life unfolds. The knowledge is regarded as progressive and not complete. Compare Philippians 3:12, and He who is calling (ὁ καλῶν, 1 Thessalonians 5:24) also ὁ ἀγαπῶν he that loves (1 John 4:7).

Hereby (ἐκ τούτου)

Not the same as the common ἐν τούτῳ (1 John 4:2). It occurs only here in the Epistle. Ἑν τούτῳ is in this: ἐκ τούτου from this. The former marks the residing or consisting of the essence or truth of a thing in something the apprehension of which conveys to us the essential nature of the thing itself. The latter marks the inference or deduction of the truth from something, as contrasted with its immediate perception in that something. Rev., by this.

The spirit of error (τὸ πνεῦμα τῆς πλάνης)

The phrase occurs nowhere else in the New Testament. Compare πνεύμασι πλάνοις misleading spirits, 1 Timothy 4:1.

{5} We are of God: he that knoweth God heareth us; he that is not of God heareth not us. Hereby know we the {e} spirit of truth, and the spirit of error.

(5) He testifies to them that his doctrine and the doctrine of his companions, is the assured word of God which of necessity we have boldly to set against all the mouths of the whole world, and thereby discern the truth from falsehood.

(e) True prophets, against whom are false prophets, that is, those who err and lead others into error.

4:6 We are of God. Hence speaks God's message, and those that know God accept the message.

Hereby know we the spirit of truth, and the spirit of error. By the principles given in 1Jo 4:2-5 we distinguish between the spirit of truth (the Holy Spirit) and that of error.

4:6 We - Apostles. Are of God - Immediately taught, and sent by him. Hereby we know - From what is said, 1Jo 4:2 -
6.

6. We-true teachers of Christ: in contrast to them.

are of God-and therefore speak of God: in contrast to "speak they of the world," 1Jo 4:5.

knoweth God-as his Father, being a child "of God" (1Jo 2:13, 14).

heareth us-Compare Joh 18:37, "Every one that is of the truth, heareth My voice."

Hereby-(1Jo 4:2-6); by their confessing, or not confessing, Jesus; by the kind of reception given them respectively by those who know God, and by those who are of the world and not of God.

spirit of truth-the Spirit which comes from God and teaches truth.

spirit of error-the spirit which comes from Satan and seduces into error.

4:1-6 Christians who are well acquainted with the Scriptures, may, in humble dependence on Divine teaching, discern those who set forth doctrines according to the apostles, and those who contradict them. The sum of revealed religion is in the doctrine concerning Christ, his person and office. The false teachers spake of the world according to its maxims and tastes, so as not to offend carnal men. The world approved them, they made rapid progress, and had many followers such as themselves; the world will love its own, and its own will love it. The true doctrine as to the Saviour's person, as leading men from the world to God, is a mark of the spirit of truth in opposition to the spirit of error. The more pure and holy any doctrine is, the more likely to be of God; nor can we by any other rules try the spirits whether they are of God or not. And what wonder is it, that people of a worldly spirit should cleave to those who are like themselves, and suit their schemes and discourses to their corrupt taste?
