Romans 10:9

"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): or, Who shall descend into the deep? (that is, to bring up Christ again from the dead.) But what saith it? The word is nigh thee, even in thy mouth, and in thy heart, that is, the word of faith which we preach. That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised Him from the dead, thou shall be saved." To prevent the Jews then from saying, How came they who had not found the lesser righteousness to find the greater? he gives a reason there was no answering, that this way was easier than that. For that requires the fulfilment of all things (for when thou doest all, then thou shall live); but the righteousness which is of faith doth not say this, but what? "If thou confess with thy mouth the Lord Jesus, and believe in thy heart that God hath raised Him from the dead, thou shalt be saved." Then again that we may not seem to be making it contemptible by showing it to be easy and cheap, observe how he expands his account of it. For he does not come immediately to the words just given, but what does he say? "But the righteousness which is of faith saith on this wise; Say not in thine heart, Who shall go up into heaven? (that is, to bring Christ down); or, Who shall descend into the deep? (that is, to bring up Christ again from the dead.)" For as to the virtue manifested in works there is opposed a listlessness, which relaxeth our labors, and it requireth a very wakeful soul not to yield to it: thus, when one is required to believe, there are reasonings which confuse and make havoc of the minds of most men, and it wants a soul of some vigor to shake them thoroughly off. And this is just why he brings the same before one. And as he did in Abraham's case, so he does here also. For having there shown that he was justified by faith, lest he should seem to have gotten so great a crown by a mere chance, as if it were a thing of no account, to extol the nature of faith, he says, "Who against hope believed in hope, that he might become the father of many nations. And being not weak in faith, he considered his own body now dead, and the deadness of Sarah's womb. He staggered not at the promise of God through unbelief; but was strong in faith, giving glory to God; and being fully persuaded that what He had promised He was able also to perform": so he showed that there is need of vigor, and a lofty soul, that takes in things beyond expectation, and stumbles not at appearances. This then he does here also, and shows that it requires a wise mind, and a spirit heavenly and great. And he does not say merely, "Say not," but, "Say not in thine heart," that is, do not so much as think of doubting and saying with thyself, And how can this be? You see that this is a chief characteristic of faith, to leave all the consequences of this lower world, and so to seek for that which is above nature, and to cast out the feebleness of calculation, and so to accept everything from the Power of God.
