Charles Ellicott Commentary Romans 11:22

"Behold then the goodness and severity of God: toward them that fell, severity; but toward thee, God`s goodness, if thou continue in his goodness: otherwise thou also shalt be cut off." — Romans 11:22 (ASV)

As Providence had been appealed to, the Apostle states the true Providential aspect of God’s rejection of Israel. It had a double side—one of goodness towards the Gentile, one of deserved severity towards the Jew. But, at the same time, the fact that the covenant was made originally with the Jew, and that he was the natural heir to the promises which it contained, is a guarantee for his restoration if he would only dismiss his unbelief.
