Romans 10:5 Meaning

3For they being ignorant of God's righteousness, and going about to establish their own righteousness, have not submitted themselves unto the righteousness of God.

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

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

6But 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:)

7Or, Who shall descend into the deep? (that is, to bring up Christ again from the dead.)
