But the righteousness which is of faith speaketh on this wise, {e} Say not in thine heart, Who shall ascend into heaven? (that is, to bring Christ down from above:)

(e) Do not think to yourself, as men that are doubting do.

People's New Testament

10:6 But the righteousness which is of faith speaketh on this wise. That is, God's righteousness in contrast with that of the law.

Say not in thine heart. The passage that follows is quoted freely from De 30:11-14. Paul modifies it somewhat in order to bring out more strongly its spiritual application. It was applied at first to certain commands addressed by Moses to Israel, but its spirit applies to the gospel.

Who shall ascend into heaven? The Jews expected a Savior, reigning upon the earth, a visible king of an earthly kingdom, and hence said,

bring Christ down from above. Bring down Christ from heaven, where you say he is, and we will believe upon him.

Wesley's Notes

10:6 But the righteousness which is by faith - The method of becoming righteous by believing. Speaketh a very different language, and may be considered as expressing itself thus: (to accommodate to our present subject the words which Moses spake, touching the plainness of his law:) Say not in thy heart, Who shall ascend into heaven, as if it were to bring Christ down: or, Who shall descend into the grave, as if it were to bring him again from the dead - Do not imagine that these things are to be done now, in order to procure thy pardon and salvation. Deut 30:14.

Jamieson-Fausset-Brown Bible Commentary

6. But the-justifying

righteousness which is of faith speaketh on this wise-"speaketh thus"-its language or import is to this effect (quoting in substance De 30:13, 14).

Say not in thine heart, Who shall ascend into heaven? that is, to bring Christ down, &c.-that is, "Ye have not to sigh over the impossibility of attaining to justification; as if one should say, oh! if I could but get someone to mount up to heaven and fetch me down Christ, there might be some hope, but since that cannot be, mine is a desperate case."

Matthew Henry's Concise Commentary

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.
