Matthew Poole and continuators on Romans 10:8

8. 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 .

i. e. What saith the Text in Deut. 30.14. Or what saith the Righteousness of Faith? what is its Stile and Language? In the sixth and seventh Verses, he did but tell us what it said not; but here he tells us what it saith.

i. e. The matter required of thee, in order to Life and Salvation: He seems in these words, to Declare the readiness, and easiness of the way of Salvation, as taught us in the Gospel, and by the Righteousness of Faith. God requires no hard thing of us; To Cross the Seas; to Climb the Mountains; to take long and painful Journeys, to find it out The way of Salvation under the Gospel hath but a short cut; it requires not so much the labour of the hand, as the confession of the mouth, and the belief of the heart; or the word that teacheth, it is at hand, it is as if it were in thy mouth and heart, a proverbial speech (as some think) to shew the readiness of it.

By the word of Faith, he means the Gospel, and the Doctrine of it: and the Gospel is so called, either effectively, because it works Faith; or objectively, because it is a received Faith, and is the proper Object of it.
