“But the righteousness which is of faith speaketh on this wise, Say not in thine heart, Who shall ascend into heaven? (that is, to bring Christ down from above:)”
King James Version (KJV)
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|.
Ro 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".
