3 For they, being ignorant of God's righteousness, and seeking to establish their own [righteousness], have not submitted to the righteousness of God. 4 For Christ is [the] end of law for righteousness to every one that believes. 5 For Moses lays down in writing the righteousness which is of the law, The man who has practised those things shall live by them. 6 But the righteousness of faith speaks thus: Do not say in thine heart, Who shall ascend to the heavens? that is, to bring Christ down; 7 or, Who shall descend into the abyss? that is, to bring up Christ from among [the] dead. 8 But what says it? The word is near thee, in thy mouth and in thy heart: that is, the word of faith, which we preach: 9 that if thou shalt confess with thy mouth Jesus as Lord, and shalt believe in thine heart that God has raised him from among [the] dead, thou shalt be saved. 10 For with [the] heart is believed to righteousness; and with [the] mouth confession made to 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.
