For Moses writes about the righteousness that is based on the law, that the person who does the commandments shall live by them. But the righteousness based on faith says, Do not say in your heart, Who will ascend into heaven? (that is, to bring Christ down) or Who will descend into the abyss? (that is, to bring Christ up from the dead). But what does it say? The word is near you, in your mouth and in your heart (that is, the word of faith that we proclaim); because, if you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved. For with the heart one believes and is justified, and with the mouth one confesses and is saved. For the Scripture says, Everyone who believes in him will not be put to shame.

And, on the limits of interpretation:
54 He also said to the crowds, When you see a cloud rising in the west, you say at once, A shower is coming. And so it happens. 55 And when you see the south wind blowing, you say, There will be scorching heat, and it happens. 56 You hypocrites! You know how to interpret the appearance of earth and sky, but why do you not know how to interpret the present time?
