Luke20:18
Whosoever shall fall upon that stone shall be broken; but on whomsoever it shall fall, it will grind him to powder.

20:9-19 Christ spake this parable against those who resolved not to own his authority, though the evidence of it was so full. How many resemble the Jews who murdered the prophets and crucified Christ, in their enmity to God, and aversion to his service, desiring to live according to their lusts, without control! Let all who are favoured with God's word, look to it that they make proper use of their advantages. Awful will be the doom, both of those who reject the Son, and of those who profess to reverence Him, yet render not the fruits in due season. Matthew Henry's Whole Bible Commentary
