And here let Christians warily distinguish betwixt the meritorious and the instrumental cause of their justification. Christ, with what he hath done and suffered, is the meritorious cause of our justification; therefore he is said to be made to us of God, "wisdom and righteousness;" and we are said to be "justified by his blood, and saved from wrath through him," for it was his life and blood that were the price of our redemption (1 Cor 1:30; Rom 5:9,10). "Redeemed," says Peter, "not with corruptible things, as silver and gold," alluding to the redemption of money under the law, "but with the precious blood of Christ." Thou art, therefore, as I have said, to make Christ Jesus the object of thy faith for justification; for by his righteousness thy sins must be covered from the sight of the justice of the law. "Believe on the Lord Jesus Christ, and thou shalt be saved." "For he shall save his people from their sins" (Acts 16:31; Matt 1:21).
Fourth. To be saved is to be preserved in the faith to the end. "He that shall endure unto the end, the same shall be saved" (Matt 24:13). Not that perseverance is an accident in Christianity, or a thing performed by human industry; they that are saved "are kept by the power of God, through faith unto salvation" (1 Peter 1:3-6).
But perseverance is absolutely necessary to the complete saving of the soul, because he that falleth short of the state that they that are saved are possessed of, as saved, cannot arrive to that saved state. He that goeth to sea with a purpose to arrive at Spain, cannot arrive there if he be drowned by the way; wherefore perseverance is absolutely necessary to the saving of the soul, and therefore it is included in the complete saving of us—"Israel shall be saved in the Lord with an everlasting salvation: ye shall not be ashamed nor confounded world without end" (Isa 45:17). Perseverance is here made absolutely necessary to the complete saving of the soul.
But, as I said, this part of salvation dependeth not upon human power, but upon him that hath begun a good work in us (Phil 1:6). This part, therefore, of our salvation is great, and calleth for no less than the power of God for our help to perform it, as will be easily granted by all those that consider—
1. That all the power and policy, malice and rage, of the devils and hell itself are against us. Any man that understandeth this will conclude that to be saved is no small thing. The devil is called a god, a prince, a lion, a roaring lion; it is said that he hath death and the power of it, &c. But what can a poor creature, whose habitation is in flesh, do against a god, a prince, a roaring lion, and the power of death itself? Our perseverance, therefore, lieth in the power of God; "the gates of hell shall not prevail against it."
2. All the world is against him that shall be saved. But what is one poor creature to all the world, especially if you consider that with the world is terror, fear, power, majesty, laws, jails, gibbets, hangings, burnings, drownings, starvings, banishments, and a thousand kinds of deaths? (1 John 5:4,5; John 16:33).
3. Add to this, that all the corruptions that dwell in our flesh are against us, and that not only in their nature and being, but they lust against us, and war against us, to "bring us into captivity to the law of sin and death" (Gal 5:17; 1 Peter 2:11; Rom 7:23).
4. All the delusions in the world are against them that shall be saved, many of which are so cunningly woven, so plausibly handled, so rarely5 polished with Scripture and reason, that it is ten thousand wonders that the elect are not swallowed up with them; and swallowed up they would be, were they not elect, and was not God himself engaged, either by power to keep them from falling, or by grace to pardon if they fall, and to lift them up again (Matt 24:24; Eph 4:14; Rom 3:12).
5. Every fall of the saved is against the salvation of his soul; but a Christian once fallen riseth not but as helped by Omnipotent power—"O Israel, thou hast fallen by thine iniquity," "but in me is thy help," says God (Hosea 13:9; 14:1; Psa 37:23).
Christians, were you awake, here would be matter of wonder to you, to see a man assaulted with all the power of hell, and yet to come off a conqueror! Is it not a wonder to see a poor creature, who in himself is weaker than the moth, to stand against and overcome all devils, all the world, all his lusts and corruptions? (Job 4:19). Or if he fall, is it not a wonder to see him, when devils and guilt are upon him, to rise again, stand upon his feet again, walk with God again, and persevere after all this in the faith and holiness of the gospel? He that knows himself, wonders; he that knows temptation, wonders; he that knows what falls and guilt mean, wonders; indeed, perseverance is a wonderful thing, and is managed by the power of God; for he only "is able to keep you from falling, and to present you faultless before the presence of his glory with exceeding joy" (Jude 24). Those of the children of Israel that went from Egypt, and entered the land of Canaan, how came they thither? Why, the text says, that "as an eagle spreadeth abroad her wings, so the Lord alone did lead them." And again, "he bore them, and carried them all the days of old" (Deu 32:11,12; Isa 63:9). David also tells us that mercy and goodness should follow him all the days of his life, and so he should dwell in the house of the Lord for ever (Psa 23:6).
