But what saith it? The word is nigh thee, even in thy mouth, and in thy heart: that is, the word of faith, which we preach; that if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised Him from the dead, thou shalt be saved. – Romans 10:8,9

The gospel speaking for itself declares, this word of life by faith in the risen Christ to be near us, that is, to be accessible to us. As your next-door neighbor’s house is not hard to get at, so neither is salvation by the gospel. It is nigh you; it is nigh you now: it will never be nigher than it is at this moment. You may now believe in Christ and live eternally. Difficulty there is none: only believe and thou art saved. It is not a mystical, obscure thing; it is near and familiar. Believe in Christ as you would believe in your friend: believe that He died for sinners, and trust in Him for salvation. If God has made you feel yourself a sinner, then Christ is such a Savior as you need, and you may have Him at once: the only difficulty lies in the way being so easy that you can hardly think it can be so. Have done with doings, and feelings, and trust yourself with Christ. “The word is nigh thee.” It is simple; indeed, so simple that people try to obscure it in order to understand it. It is such milk for babes that I have known people refuse such plain truth because they were not willing to be treated like little children. Just as I lean all my weight upon this rail so do I lean my soul wholly upon Christ. If what Christ has done will not save a sinner I am damned; for I have nothing else to depend upon; but if it will save, and sure I am that it will, I am saved as surely as Christ has risen from the dead. This is the substance of the matter-Christ saves, and we trust. This is what that word of faith says, even the gospel which we preach. I am afraid we say a great deal at times which rather lumbers and cumbers the gospel than makes it clear. Perhaps I am doing the same this morning, but I do not mean to do it. I mean to let it stand out simply before you, that the incarnation, the life, the death, and the resurrection of Christ are the one foundation upon which we must depend for eternal salvation, and upon that alone; and if we do so depend we shall most assuredly be saved. ~ C.H. Spurgeon

Say not in thine heart, Who shall ascend into heaven? (that is, to bring Christ down from above:) Or, Who shall descend into the deep? (that is, to bring up Christ again from the dead.) – Romans 10:6,7

A voice cries “Who shall ascend into heaven?” The gospel replies, if you did ascend to heaven what would you do there, without Christ, the anointed Savior? You say, “Who shall descend into the deep?” Listen, man. If you were to descend there, what would you do without Him whom God has anointed to save? If you find Him it will not much matter where you find Him, in heaven or in the deep, for He must be almighty everywhere. Now hearken. Thou sayest, “Who shall ascend into heaven?” the top and bottom of such an ascent must be, “to bring Christ down.” Hear this! Jesus has come down: years ago He left the glories of His Father…Oh, my hearer, our salvation lies in this! Not in our descending, but in Christ’s descending our hope is to be found. Listen to it, lost ones; you need not climb to heaven: Christ has come down from heaven to you; and if you lie among the spiritually dead to-day, or think you do, He has come down to you, and you need not enquire how you can go up to Him. No prayers, or tears, are wanted to bring Him down: He has already come and is near at hand… You need not “bring up Christ again from the dead,” for the Lord has risen indeed…He has gone up to the Father’s throne, as the sinner’s Savior: at the throne He stands to-day to intercede for sinners, and from that throne He bends to comfort those who come to Him. Now, your hope lies wholly in what this Son of God did in His descent and ascent. God has brought Him again from the dead and exalted Him at His own right hand, and this is not for Himself, but for all those who trust in Him. His death is instead of the death of our souls: His life is the life of our spirits. Now, soul, thou hast nothing to do with asking vain questions; thou hast to accept the result of the Savior’s actual performances. The saving work is done, done by Him who was anointed of the Lord to do it. ~ C.H. Spurgeon

For Christ is the end of the law for righteousness to every one that believeth. – Romans 10:4

“I counsel you to buy from Me gold refined in the fire, that you may be rich; and white garments, that you may be clothed, that the shame of your nakedness may not be revealed; and anoint your eyes with eye salve, that you may see. – Revelation 3:18

The righteousness of faith lies not in dreams and visions, delusions or depressions: it lies only in reliance upon the work of Jesus finished for you. Go not to the loom to weave a righteousness. The garment is woven already; put it on; Christ gives it to you. Dig not into the bowels of the earth to find the gold of salvation. Christ holds it out to you: take it freely and be rich for ever. 

The top and bottom of the matter is, “Believe in the Lord Jesus Christ.” Be nothing; be nobody; and trust Him. Do not believe in yourself but believe in Jesus. Have as many good works as you can cram into your life, but never tell anybody about them, or think anything of them. The best of them are but filthy rags: stow them all away in the coal-hole, and look to the merits of your Lord for salvation. Go to Jesus for everything. He says, “I counsel thee to buy of Me gold tried in the fire, that thou may be rich; and white raiment, that thou mayest be clothed.” Take His counsel. ~ C.H. Spurgeon

“For this commandment which I command thee this day, it is not hidden from thee, neither is it far off...But the word is very nigh unto thee, in thy mouth, and in thy heart, that thou mayest do it.” – Deuteronomy 30:11-14

“The righteousness which is of faith, speaketh on this wise…The word is nigh thee, even in thy mouth, and in thy heart: that is, the word of faith, which we preach; that if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised Him from the dead, thou shalt be saved.” – Romans 10:5-9

The gospel by no means involves itself in obscurity, but says, Believe and live, quite as distinctly as Moses said, “Do and live.” Here you have it, “Believe in the Lord Jesus Christ, and thou shalt be saved.” Moses’ utterance was single and by itself. He did not say, “Do and thou shalt live, and yet there is another way.” No; under the law it was nothing but “Do and live; leave undone and die.” So the gospel does not propose a second way, and suggest “a larger hope,” but it declares with solemn decision, “He that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God.” It is just as clear as ever the law was, and quite as sharply distinct. Herein is no mystery: Jesus Christ came into the world to save sinners, and whosoever believeth in Him shall not perish, but have everlasting life. Wrapping everything up into one, the gospel says, “Trust thou in the Lord Jesus Christ, and thy sins shall be forgiven thee, and thou shalt be saved.” This believing, or trusting, is the whole of the matter, and neither heaven above nor the abyss beneath will ever reveal another salvation. ~ C.H. Spurgeon

For Moses describeth the righteousness which is of the law, That the man which doeth those things shall live by them. – Romans 10:5

Judge ye whether any one of us has fulfilled the whole law. To my mind this word of Moses is conclusive that none of us can possibly live by the works of the law. We cannot keep the law now, for we have already broken it: the vase is fractured, and to talk of keeping it entire is nonsense. But even if it were not already broken, should we get through to-morrow with its temptations, bearing such a heart as we have within us, without breaking that perfect and spotless law? I am sure we should not. You that hope to be saved by your works are indulging a forlorn hope; what never you may do or be in the future, the past has already ruined you…The hope of salvation by works is black despair; yet we have a set of men on the face of the earth who are always wanting us to preach up this hopeless hope and urging us to lay this heavy burden upon the shoulders of dying men. They would have us proclaim salvation by the works of the law. This, they say, would at least make men moral and keep them sober: whereas even in this they err against the light; for it has been proved by history that such preaching makes men worse and worse. The idea of salvation by works sits like an awful incubus upon the breast of humanity, and presses out of the soul all hope, thus robbing man of strength to attempt true holiness…Clear, then, as possible it must be to every man among us who will think, that if the only way of salvation by the works of the law is by the keeping of the law in its entirety, then that road is closed against us, and the sooner we have done with it the better; for then we shall turn our thoughts in the right direction, and travel on the way which the Lord in great mercy has prepared for us.

That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised Him from the dead, thou shalt be saved. Romans 10:9

~ C.H. Spurgeon

For Moses describeth the righteousness which is of the law, That the man which doeth those things shall live by them. – Romans 10:5

If you wish to be saved by the law you must do its commands and you shall live. The law is written in the ten commandments; you know them; and if you desire to live by them you must keep them. It will not suffice for you to learn those commands by heart, or to write them up in your churches, or to read them over and say, “Lord, have mercy upon us, and incline our hearts to keep this law”: all that may be well enough, but it is not to the point. If you are to be saved by the commandments you must do them: that is clear. Moses does not allow any person to dream that under the law he can be saved in any other way than by perfect obedience thereto. “For not the hearers of the law are just before God, but the doers of the law shall be justified.” Whatever it is that God has commanded, you must do; whatever He forbids, you must avoid; for by such obedience alone can you live.

Christ’s fullness is meant for our emptiness; Christ’s righteousness is meant for our sin; salvation is for the lost. When you and I are no longer sinners, Christ is no longer our Savior; when you and I no more need Him, then we shall not have Him. Our need is our warrant, and if that be gone, all is gone. Jesus did not bleed and die to be a superfluity to us: He came to meet a grim necessity. As long as we are nothing Christ is our all in all; we may be sure of that, and that is just the gospel in a nutshell…Jesus came into the world to save real sinners, not sham sinners; for He is a real, and not a pretended Savior. He saves those who are always confessors of sin, always needy in themselves, and therefore always glad of Him. Even in their best estate the saved ones need their Lord: even if we walk in the light as God is in the light, and have fellowship with Him, we still sin, and still the blood of Jesus Christ, His Son, cleanseth us from all sin. ~ C.H. Spurgeon
