But he who doeth truth This appears to be an improper and absurd statement, unless you choose to admit that some are upright and true, before they have been renewed by the Spirit of God, which does not at all agree with the uniform doctrine of Scripture; for we know that faith is the root from which the fruits of good works spring. To solve this difficulty, Augustine says, that to do truth means "to acknowledge that we are miserable and destitute of all power of doing good;" and, certainly, it is a true preparation for faith, when a conviction of our poverty compels us to flee to the grace of God. But all this is widely removed from Christ's meaning, for he intended simply to say that those who act sincerely desire nothing more earnestly than light, that their works may be tried; because, when such a trial has been made, it becomes more evident that, in the sight of God, they speak the truth and are free from all deceit. Now it would be inconclusive reasoning, were we to infer from this, that men have a good conscience before they have faith; for Christ does not say that the elect believe, so as to deserve the praise of good works, but only what unbelievers would do, if they had not a bad conscience. Christ employed the word truth, because, when we are deceived by the outward lustre of works, we do not consider what is concealed within. Accordingly, he says, that men who are upright and free from hypocrisy willingly go into the presence of God, who alone is the competent Judge of our works. For those works are said to be done in God or according to God, which are approved by Him, and which are good according to His rule. Hence let us learn that we must not judge of works in any other way than by bringing them to the light of the Gospel, because our reason is wholly blind.

Are that doeth truth - He who does right, or he that obeys the truth. Truth here is opposed to error and to evil. The sinner acts from falsehood and error. The good man acts according to truth. The sinner believes a lie - that God will not punish, or that there is no God, or that there is no eternity and no hell. The Christian believes all these, and acts as if they were true. This is the difference between a Christian and a sinner.
Cometh to the light - Loves the truth, and seeks it more and more. By prayer and searching the Scriptures he endeavors to ascertain the truth, and yield his mind to it.
May be made manifest - May be made clear or plain; or that it may be made plain that his deeds are performed in God. He searches for truth and light that he may have evidence that his actions are right.
Wrought in God - That they are performed according to the will of God, or perhaps by the assistance of God, and are such as God will approve. The actions of good people are performed by the influence and aid of God, Philippians 2:12. Of course, if they are performed by his aid, they are such as he will approve. Here is presented the character of a good man and a sincere Christian. We learn respecting that character:
1. He does truth. He loves it, seeks it, follows it.
2. He comes to the light. He does not attempt to deceive himself or others.
3. He is willing to know himself, and aims to do it. He desires to know the true state of his heart before God.
4. A special object of his efforts is that his deeds may be "wrought in God." He desires to be a good man; to receive continual aid from God, and to perform such actions as he will approve.
This is the close of our Lord's discourse with Nicodemus - a discourse condensing the gospel, giving the most striking exhibition and illustration of truth, and representing especially the fundamental doctrine of regeneration and the evidence of the change. It is clear that the Saviour regarded this as lying at the foundation of religion. Without it we cannot possibly be saved. And now it becomes every reader, as in the presence of God, and in view of the judgment-seat of Christ, solemnly to ask himself whether he has experienced this change? whether he knows by experience what it is to be born of that Spirit? If he does he will be saved. If not, he is in the gall of bitterness and in the bond of iniquity, and should give no sleep to his eyes until he has made his peace with God.

Wrought in God - In his presence, and through his assistance. This is the end of our Lord's discourse to Nicodemus; and though we are not informed here of any good effects produced by it, yet we learn from other scriptures that it had produced the most blessed effects in his mind, and that from this time he became a disciple of Christ. He publicly defended our Lord in the Sanhedrin, of which he was probably a member, John 7:50, and, with Joseph of Arimathea, gave him an honorable funeral, John 19:39, when all his bosom friends had deserted him. See Dodd.

But he that (s) doeth truth cometh to the light, that his deeds may be made manifest, that they are wrought (t) in God.
(s) That is, he that leads an honest life, and is void of all cunning and deceit.
(t) That is, with God, God as it were going before.

But he that doth truth,.... That which is true, right and good: "he whose work is just", as the Ethiopic version renders it; or, "he that does that which is right", so the Persic; that which is according to the will of God, and from a principle of love to him, and with a view to his glory:
cometh to the light; to Christ, and to his word, and ordinances:
that his deeds may be made manifest; being brought to the light, to the test, and standard, whether they, are right, or wrong; and that it may appear,
that they are wrought in God; or "by God"; by his assistance, and gracious influence, without which men can do nothing; for it is God that works in them both to will and to do: or, "according to God", as others render it; according to the will of God, both for matter and manner: or "for God", as the Ethiopic version renders it; for the glory of God, which ought to be the aim, and end of every action. The Persic version reads the whole thus, "that the work which is between God and him may be known"; that such deeds may be discovered, which are only known to God and himself.

doeth truth--whose only object in life is to be and do what will bear the light. Therefore he loves and "comes to the light," that all he is and does, being thus thoroughly tested, may be seen to have nothing in it but what is divinely wrought and divinely approved. This is the "Israelite, indeed, in whom is no guile."

He that doeth truth. Truth has to be lived. He who lives it, lives an honest life sincerely desiring light, will come to the light.

He that practiseth the truth (that is, true religion) cometh to the light - So even Nicodemus, afterward did. Are wrought in God - That is, in the light, power, and love of God.
