Featured Regeneration happens at the same time as saving faith is given,

CHS preached this:
And now we must say, that regeneration consists in this. God the Holy Spirit, in a supernatural manner—mark, by the word supernatural I mean just what it strictly means; supernatural, more than natural—works upon the hearts of men, and they by the operations of the divine Spirit become regenerate men; but without the Spirit they never can be regenerated. And unless God the Holy Spirit, who "worketh in us to will and to do," should operate upon the will and the conscience, regeneration is an absolute impossibility, and therefore so is salvation. "What!" says one, "do you mean to say that God absolutely interposes in the salvation of every man to make him regenerate?" I do indeed; in the salvation of every person there is an actual putting forth of the divine power, whereby the dead sinner is quickened, the unwilling sinner is made willing, the desperately hard sinner has his conscience made tender; and he who rejected God and despised Christ, is brought to cast himself down at the feet of Jesus. This is called fanatical doctrine, mayhap; that we can not help; it is scriptural doctrine, that is enough for us. "Except a man be born of the Spirit he can not see the kingdom of God; that which is born of the flesh is flesh, and that which is born of the Spirit is spirit." If you like it not, quarrel with my Master, not with me; I do but simply declare his own revelation, that there must be in your heart something more than you can ever work there. There must be a divine operation; call it a miraculous operation, if you please; it is in some sense so. There must be a divine interposition, a divine working, a divine influence, or else, do what you may, without that you perish, and are undone; "for except a man be born again, be can not see the kingdom of God." The change is radical; it gives us new natures, makes us love what we hated and hate what we loved, sets us in a new road; makes our habits different, our thoughts different, makes us different in private, and different in public. So that being in Christ it is fulfilled: "If any man be in Christ he is a new creature; old things are passed away, behold all things are become new."

pt2:
Why, he cannot see the kingdom of God, because he would be out of place in heaven. A man that is not born again could not enjoy heaven. There is an actual impossibility in his nature, which prevents him from enjoying any of the bliss of Paradise. You think, mayhap, that heaven consists in those walls of jewels, in those pearly gates, and gates of gold; not so, that is the habitation of heaven. Heaven dwells there, but that is not heaven. Heaven is a state that is made here, that is made in the heart; made by God's Spirit within us, and unless God the Spirit has renewed us, and caused us to be born again, we cannot enjoy the things of heaven.

Why, it is a physical impossibility that ever a swine should deliver a lecture on astronomy; every man will clearly perceive that it must be impossible that a snail should build a city; and there is just as much impossibility that a sinner unmended, should enjoy heaven. Why, there would be nothing there for him to enjoy; if he could be put into the place where heaven is, he would be miserable; he would cry, "Let me away, let me away; let me away from this miserable place!"

I appeal to yourselves; a sermon is too long for you very often; the singing of God's praises is dull, dry work; you think that going up to God's house is very tedious. What will you do where they praise God day without night? If just a short discourse here is very wearying, what will you think of the eternal talkings of the redeemed through all ages of the wonders of redeeming love? If the company of the righteous is very irksome to you, what will be their company throughout eternity? I think many of you are free to confess that psalm singing is not a bit to your taste, that you care naught about any spiritual things; give you your bottle of wine, and set you down at your ease, that is heaven for you! Well, there is no such a heaven yet made; and therefore there is no heaven for you. The only heaven there is, is the heaven of spiritual men, the heaven of praise, the heaven of delight in God, the heaven of acceptance in the beloved, the heaven of communion with Christ. Now, you do not understand any thing about this; you could not enjoy it if you were to have it; you have not the capabilities for doing so. You, yourselves, from the very fact of your not being born again, are your own barrier to heaven, and if God were to open the gate wide, and say, "Come in," you could not enjoy heaven, if you were admitted; for unless a man be born again, there is an impossibility, a moral impossibility, of his seeing the kingdom of God.
Suppose there are some persons here who are entirely deaf, who have never heard sounds; well, I say they cannot hear singing. Do I when I say it, say a cruel thing? It is their own disability that prevents them. So when God says you cannot see the kingdom of heaven, he means that it is your own disability for the enjoyment of heaven, that will prevent you ever entering there.



Our life is like that wax melting in the flame; death puts its stamp on it, and then it cools, and the impress never can be changed. You to day are like the burning metal running forth from the cauldron in the mold; death cools you in your mold, and you are cast in that shape throughout eternity. The voice of doom crieth over the dead, "He that is holy let him be holy still; he that is unjust let him be unjust still; he that is filthy, let him be filthy still." The damned are lost forever; they can not be born again; they go on cursing, ever being cursed; ever fighting against God, and ever being trampled beneath his feet; they go on ever mocking, ever being laughed at for their mockery; ever rebelling and ever being tortured with the whips of conscience, because they are ever sinning. They cannot be regenerated because they are dead.

 

In another sermon CHS was very clear.
Inasmuch as the gospel command, "Believe in the Lord Jesus Christ and thou shalt be saved," is addressed by divine authority to every creature, it is the duty of every man so to do. What saith John: "This is his commandment, That we should believe on the name of his Son Jesus Christ," and our Lord himself assures us, "He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only-begotten Son of God."

I know there are some who will deny this, and deny it upon the ground that man has not the spiritual ability to believe in Jesus, to which I reply that it is altogether an error to imagine that the measure of the sinners moral ability is the measure of his duty. There are many things which men ought to do which they have now lost the moral and spiritual, though not the physical, power to do.

A man ought to be chaste, but if he has been so long immoral that he cannot restrain his passions, he is not thereby free from the obligation.

It is the duty of a debtor to pay his debts, but if he has been such a spendthrift that he has brought himself into hopeless poverty, he is not exonerated from his debts thereby. Every man ought to believe that which is true, but if his mind has become so depraved that he loves a lie and will not receive the truth, is he thereby excused?

If the law of God is to be lowered according to the moral condition of sinners, you would have a law graduated upon a sliding- scale to suit the degrees of human sinfulness; in fact, the worst man would be under the least law, and become consequently the least guilty. God's requirements would be a variable quantity, and, in truth, we should be under no rule at all.


The command of Christ stands good however bad men may be, and when he commands all men everywhere to repent, they are bound to repent, whether their sinfulness renders it impossible for them to be willing to so or not. In every case it is man's duty to do what God bids him.

At the same time, this faith, wherever it exists, is in every case, without exception, the gift of God and the work of the Holy Spirit. Never yet did a man believe in Jesus with the faith here intended, except the Holy Spirit led him to do so. He has wrought all our works in us, and our faith too.

Faith is too celestial a grace to spring up in human nature till it is renewed: faith is in every believer "the gift of God." You will say to me, "Are these two things consistent?" I reply, "Certainly, for they are both true." "How consistent?" say you. "How inconsistent?" say I, and you shall have as much difficulty to prove them inconsistent as I to prove them consistent. Experience makes them consistent, if theory does not. Men are convinced by the Holy Spirit of sin—"of sin," saith Christ, "because they believe not on me;" here is one of the truths; but the selfsame hearts are taught the same Spirit that faith is of the operation of God. (Col. ii. 2) Brethren be willing to see both sides of the shield of truth. Rise above the babyhood which cannot believe two doctrines until it sees the connecting link. Have you not two eyes, man? Must you needs put one of them out in order to see clearly? Is it impossible to you to use a spiritual stereoscope, and look at two views of truth until they melt into one, and that one becomes more real and actual because it is made up of two? Many men refuse to see more than one side of a doctrine, and persistently fight against anything which is not on its very surface consistent with their own idea. In the present case I do not find it difficult to believe faith to be at the same time the duty of man and the gift of God; and if others cannot accept the two truths, I am not responsible for their rejection of them; my duty is performed when I have honestly borne witness to them.
