Chrysostom says: "Do you see the power of freedom? Do you see the authority of the will? Nothing is unchangeable, neither your good, O Gentile, nor his evil, O Jew. Do you see how the Apostle raised up the despairing Jew and humbled the self-confident Gentile?
"You, O Jew, when you hear of severity, do not despair. You, O Gentile, when you hear of goodness, do not trust in yourself. He did not spare you and cut you off in order that you might desire to return. To you He showed grace so that you might remain.
"The Apostle did not say, 'in faith,' but 'in goodness,' that is, so that you may do what is worthy of God's love for mankind. Faith alone is not required. Do you notice how the Apostle does not allow the fallen to lie still, nor the others to think highly of themselves?
"On the contrary, he stirs the former to emulation. From the example of the Gentiles he shows the Jew the possibility of standing once more in the place of the Gentile, since the Gentile has taken the Jew's place in advance.
"He frightens the Gentiles, so that they may not exalt themselves over the Jews, by the example of the Jews and by what happened to them. He gives courage to the Jew by what was done for the Greek. You also will be cut off, the Apostle says to the Gentile, if you grow careless.
"The Jew was cut off, but he will be grafted in if he is zealous, because you too were grafted in. The Apostle acts very wisely in directing the whole discourse to the Gentile. In his usual way, by striking the stronger, he corrects the weaker.
"Then, so that the order of his reasoning may not be disputed, he takes his proof from the almighty power of God. Although the Jews were cut off and rejected, and although others took their place, they must not despair for all that.
"For God is able, he says, to graft them in again. God is able to do even what is beyond hope. But if you require proofs from experience, you have a most sufficient example in yourself."
