He who believeth in him is not condemned. When he so frequently and so earnestly repeats, that all believers are beyond danger of death, we may infer from it the great necessity of firm and assured confidence, that the conscience may not be kept perpetually in a state of trembling and alarm. He again declares that, when we have believed, there is no remaining condemnation, which he will afterwards explain more fully in the Fifth Chapter. The present tense -- is not condemned -- is here used instead of the future tense -- shall not be condemned -- according to the custom of the Hebrew language; for he means that believers are safe from the fear of condemnation. But he who believeth not is condemned already This means that there is no other remedy by which any human being can escape death; or, in other words, that for all who reject the life given to them in Christ, there remains nothing but death, since life consists in nothing else than in faith. The past tense of the verb, is condemned already, (ede kekritai,) was used by him emphatically, (emphatikos,) to express more strongly that all unbelievers are utterly ruined. But it ought to be observed that Christ speaks especially of those whose wickedness shall be displayed in open contempt of the Gospel. For though it is true that there never was any other remedy for escaping death than that men should betake themselves to Christ, yet as Christ here speaks of the preaching of the Gospel, which was to be spread throughout the whole world, he directs his discourse against those who deliberately and maliciously extinguish the light which God had kindled.

He that believeth - He that has confidence in him; that relies on him; that trusts to his merits and promises for salvation. To believe on him is to feel and act according to truth that is, to go as lost sinners, and act toward him as a Saviour from sins; relying on him, and looking to him "only" for salvation. See the notes at Mark 16:16.
Is not condemned - God pardons sin, and delivers us from deserved punishment, because we believe on him. Jesus died in our stead; he suffered for us, and by his sufferings our sins are expiated, and it is consistent for God to forgive. When a stoner, therefore, believes on Jesus, he trusts in him as having died in his place, and God having accepted the offering which Christ made in our stead, as being an equivalent for our sufferings in hell, there is now no further condemnation, Romans 8:1.
He that believeth not - All who do not believe, whether the gospel has come to them or not. All people by nature.
Is condemned already - By conscience, by law, and in the judgment of God. God disapproves of their character, and this feeling of disapprobation, and the expression of it, is the condemnation. There is no condemnation so terrible as this - that God disapproves our conduct, and that he will express his disapprobation. He will judge according to truth, and woe to that man whose conduct God cannot approve.
Because - This word does not imply that the ground or reason of their condemnation is that they have not believed, or that they are condemned because they do not believe on him, for there are millions of sinners who have never heard of him; but the meaning is this: There is but one way by which men can be freed from condemnation. All people without the gospel are condemned. They who do not believe are still under this condemnation, not having embraced the only way by which they can be delivered from it. The verse may be thus paraphrased: "All people are by nature condemned. There is but one way of being delivered from this state by believing on the Son of God. They who do not believe or remain in that state are still condemned, for they have not embraced the only way in which they can be freed from it. Nevertheless, those to whom the gospel comes greatly heighten their guilt and condemnation by rejecting the offers of mercy, and trampling under foot the blood of the Son of God, Luke 12:47; Matthew 11:23; Hebrews 10:29; Proverbs 1:24-30. And there are thousands going to eternity under this "double" condemnation:
1. for positive, open sin; and,
2. for rejecting God's mercy, and despising the gospel of his Son. This it is which will make the doom of sinners in Christian lands so terrible.

He that believeth - As stated before on John 3:16.
Is not condemned - For past sin, that being forgiven on his believing in Christ.
But he that believeth not - When the Gospel is preached to him, and the way of salvation made plain.
Is condemned already - Continues under the condemnation which Divine justice has passed upon all sinners; and has this superadded, He hath not believed on the name of the only begotten Son of God, and therefore is guilty of the grossest insult to the Divine majesty, in neglecting, slighting, and despising the salvation which the infinite mercy of God had provided for him.

He that believeth on him is not condemned,.... Whether Jew or Gentile, because a believer is openly in Christ; and there is no condemnation to those that are in him: and though the sentence of death passed upon all in Adam, and judgment came upon all men to condemnation in him; yet this sentence being executed on Christ, the surety of his people, who has been condemned to death, and has suffered it in their stead, his death is a security to them from all condemnation: and they are delivered by him from the curse and condemnation of the law: and having in conversion openly passed from death to life, they shall never enter into condemnation; and this is the happy case of every one that believes in Christ:
but he that believeth not is condemned already. The Persic version renders it, "from the beginning"; he remains under the sentence of condemnation passed in Adam upon him; the law accuses him, and pronounces him guilty before God; he is under the curse of it, and it is a ministration of condemnation and death to him; nor has he any thing to secure him from its charge, curse, and condemnation: this must be understood of one that is a final unbeliever, or that lives, and dies, in a state of impenitence, and unbelief:
because he hath not believed in the name of the only begotten Son of God; whom God has sent to be the Saviour of lost sinners, and to deliver them from wrath to come; and there is no other name but his, whereby men can be saved; so that such that do not believe in him, must be damned.

How great is the sin of unbelievers! God sent One to save us, that was dearest to himself; and shall he not be dearest to us? How great is the misery of unbelievers! they are condemned already; which speaks a certain condemnation; a present condemnation. The wrath of God now fastens upon them; and their own hearts condemn them. There is also a condemnation grounded on their former guilt; they are open to the law for all their sins; because they are not by faith interested in the gospel pardon. Unbelief is a sin against the remedy. It springs from the enmity of the heart of man to God, from love of sin in some form. Read also the doom of those that would not know Christ. Sinful works are works of darkness. The wicked world keep as far from this light as they can, lest their deeds should be reproved. Christ is hated, because sin is loved. If they had not hated saving knowledge, they would not sit down contentedly in condemning ignorance. On the other hand, renewed hearts bid this light welcome. A good man acts truly and sincerely in all he does. He desires to know what the will of God is, and to do it, though against his own worldly interest. A change in his whole character and conduct has taken place. The love of God is shed abroad in his heart by the Holy Ghost, and is become the commanding principle of his actions. So long as he continues under a load of unforgiven guilt, there can be little else than slavish fear of God; but when his doubts are done away, when he sees the righteous ground whereon this forgiveness is built, he rests on it as his own, and is united to God by unfeigned love. Our works are good when the will of God is the rule of them, and the glory of God the end of them; when they are done in his strength, and for his sake; to him, and not to men. Regeneration, or the new birth, is a subject to which the world is very averse; it is, however, the grand concern, in comparison with which every thing else is but trifling. What does it signify though we have food to eat in plenty, and variety of raiment to put on, if we are not born again? if after a few mornings and evenings spent in unthinking mirth, carnal pleasure, and riot, we die in our sins, and lie down in sorrow? What does it signify though we are well able to act our parts in life, in every other respect, if at last we hear from the Supreme Judge, "Depart from me, I know you not, ye workers of iniquity?"

is not condemned--Having, immediately on his believing, "passed from death unto life" (John 5:24).
condemned already--Rejecting the one way of deliverance from that "condemnation" which God gave His Son to remove, and so wilfully remaining condemned.

He that believeth on him is not condemned. "He that believeth and is baptized shall be saved." Faith in Christ is essential to salvation, because it is the power that leads to obedience to him.
Is condemned already. "He that believeth not shall be damned." The unbeliever condemns himself. He is lost and refuses to be saved by Christ.

He that believeth on him is not condemned - Is acquitted, is justified before God. The name of the only - begotten Son of God - The name of a person is often put for the person himself. But perhaps it is farther intimated in that expression, that the person spoken of is great and magnificent. And therefore it is generally used to express either God the Father or the Son.
