Luke 16:15, 17, 31

And he said unto them, Ye are they which justify yourselves before men; but God knoweth your hearts: for that which is highly esteemed among men is abomination in the sight of God.

And it is easier for heaven and earth to pass, than one tittle of the law to fail.

And he said unto him, If they hear not Moses and the prophets, neither will they be persuaded, though one rose from the dead.
