That speaketh of himself - This does not mean about or concerning himself, but he that speaks by his own authority, without being sent by God, as mere human teachers do.

Seeketh his own glory - His own praise, or seeks for reputation and applause. This is the case with mere human teachers, and as Jesus in his discourses manifestly sought to honor God, they ought to have supposed that he was sent by him.

No unrighteousness - This word here means, evidently, there is no falsehood, no deception in him. He is not an impostor. It is used in the same sense in 2 Thessalonians 2:10-12. It is true that there was no unrighteousness, no sin in Jesus Christ, but that is not the truth taught here. It is that he was not an impostor, and the evidence of this was that he sought not his own glory, but the honor of God. This evidence was furnished:

1. in his retiring, unobtrusive disposition; in his not seeking the applause of people;

2. in his teaching such doctrines as tended to exalt God and humble man;

3. in his ascribing all glory and praise to God;

He that speaketh of himself, etc. - I will give you another rule, whereby you shall know whether I am from God or not: If I speak so as to procure my own glory, to gratify vanity, or to secure and promote my secular interests, then reject me as a deceiver and as a false prophet. But if I act only to promote the glory of God, to induce all men to love and obey him; if I propose nothing but what leads to the perfection of his law, and the accomplishment of its ordinances, you cannot help acknowledging me at least for a true prophet; and, if you add to this the proofs which I have given of my mission and power, you must acknowledge me as the mighty power of God, and the promised Messiah.

And no unrighteousness is in him - Or, there is no falsehood in him: so the word αδικια should be translated here; and it is frequently used by the Septuagint for שקר sheker, a lie, falsehood, etc. See in Psalm 52:3; Psalm 119:29, Psalm 119:69, Psalm 119:104, Psalm 119:163; Psalm 144:8. This is its meaning in Romans 2:8; where αδικια, falsehood, is put in opposition to αληθεια, truth.

He that speaketh of himself,..... What he himself has devised, and is a scheme of his own; for which he has no divine warrant and commission:

seeketh his own glory; honour and applause from men; as did the Scribes and Pharisees, who taught for doctrines the commandments of men, the traditions of the elders, their own glosses upon the law, and their own decisions and determinations: and as did the false teachers, who had nothing else in view but themselves, their worldly interest, or vain glory; these suited their doctrines to the minds and lusts of men, in order to gain their point:

but he that seeketh his glory that sent him; that gave him in commission what he should say and speak, and his only; as did Christ, and so his apostles after him:

the same is true, and no unrighteousness is in him; he is an upright and faithful man, and what he says is truth; he brings true doctrine along with him, and there is no fraud or imposture in him; nor any insincerity "in his heart", as the Syriac and Persic versions render it; nor any dishonesty in his conduct; he is no cheat or deceiver; was he, he would seek his own glory and interest; but as he appears to be a man of no design, his doctrine is to be depended on and received; and such was Christ.

His own glory (τὴν δόξαν τὴν ἰδίαν)

Literally, the glow which is His own; the second article throwing His own into sharp contrast with His that sent Him. On His own, see on Acts 1:7; see on Matthew 22:5; see on Matthew 25:15.

The same (οὖτος)

Notice the characteristic use of the pronoun taking up and emphasizing the principal subject of the sentence.

Unrighteousness (ἀδικία)

See on 2 Peter 2:13.

{6} He that speaketh of himself seeketh his own glory: but he that seeketh his glory that sent him, the same is true, and no unrighteousness is in him.

(6) The true doctrine of salvation differs from the false in this, that the true doctrine sets forth the glory of God, and the false doctrine by puffing up men, dishonouring the glory of God.

7:18 There is no unrighteousness in him - No deceit or falsehood.

18. seeketh his own glory-(See on [1800]Joh 5:41-44).

7:14-24 Every faithful minister may humbly adopt Christ's words. His doctrine is not his own finding out, but is from God's word, through the teaching of his Spirit. And amidst the disputes which disturb the world, if any man, of any nation, seeks to do the will of God, he shall know whether the doctrine is of God, or whether men speak of themselves. Only those who hate the truth shall be given up to errors which will be fatal. Surely it was as agreeable to the design of the sabbath to restore health to the afflicted, as to administer an outward rite. Jesus told them to decide on his conduct according to the spiritual import of the Divine law. We must not judge concerning any by their outward appearance, but by their worth, and by the gifts and graces of God's Spirit in them.
