3 Because, not having knowledge of God's righteousness, and desiring to give effect to their righteousness, they have not put themselves under the righteousness of God. 4 For Christ is the end of the law for righteousness to everyone who has faith. 5 For Moses says that the man who does the righteousness which is of the law will get life by it. 6 But the righteousness which is of faith says these words, Say not in your heart, Who will go up to heaven? (that is, to make Christ come down:) 7 Or, Who will go down into the deep? (that is, to make Christ come again from the dead:) 8 But what does it say? The word is near you, in your mouth and in your heart: that is, the word of faith of which we are the preachers: 9 Because, if you say with your mouth that Jesus is Lord, and have faith in your heart that God has made him come back from the dead, you will have salvation: 10 For with the heart man has faith to get righteousness, and with the mouth he says that Jesus is Lord to get salvation.
Matthew Henry's Commentary on Romans 10:3-10
Commentary on Romans 10:1-4
(Read Romans 10:1-4)
The Jews built on a false foundation, and refused to come to Christ for free salvation by faith, and numbers in every age do the same in various ways. The strictness of the law showed men their need of salvation by grace, through faith. And the ceremonies shadowed forth Christ as fulfilling the righteousness, and bearing the curse of the law. So that even under the law, all who were justified before God, obtained that blessing by faith, whereby they were made partakers of the perfect righteousness of the promised Redeemer. The law is not destroyed, nor the intention of the Lawgiver disappointed; but full satisfaction being made by the death of Christ for our breach of the law, the end is gained. That is, Christ has fulfilled the whole law, therefore whoever believeth in him, is counted just before God, as much as though he had fulfilled the whole law himself. Sinners never could go on in vain fancies of their own righteousness, if they knew the justice of God as a Governor, or his righteousness as a Saviour.
Commentary on Romans 10:5-11
(Read Romans 10:5-11)
The self-condemned sinner need not perplex himself how this righteousness may be found. When we speak of looking upon Christ, and receiving, and feeding upon him, it is not Christ in heaven, nor Christ in the deep, that we mean; but Christ in the promise, Christ offered in the word. Justification by faith in Christ is a plain doctrine. It is brought before the mind and heart of every one, thus leaving him without excuse for unbelief. If a man confessed faith in Jesus, as the Lord and Saviour of lost sinners, and really believed in his heart that God had raised him from the dead, thus showing that he had accepted the atonement, he should be saved by the righteousness of Christ, imputed to him through faith. But no faith is justifying which is not powerful in sanctifying the heart, and regulating all its affections by the love of Christ. We must devote and give up to God our souls and our bodies: our souls in believing with the heart, and our bodies in confessing with the mouth. The believer shall never have cause to repent his confident trust in the Lord Jesus. Of such faith no sinner shall be ashamed before God; and he ought to glory in it before men.
