Romans 11:20-22

20Well; by their unbelief they were broken off, and thou standest by thy faith. Be not highminded, but fear: 21for if God spared not the natural branches, neither will he spare thee. 22Behold 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.
