.And the Pharisees also, who were covetous, heard all these things: and they derided Him.  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.  The law and the prophets were until John: since that time the kingdom of God is preached, and every man presseth into it.  And it is easier for heaven and earth to pass, than one tittle of the law to fail.”
Luke 16:14-17

Jesus is rebuking those Pharisees who at about every point Jesus made  to them they excused themselves, justifying their actions, seeing themselves as better than any of the people they were supposed to be ministers to.  What is looked on highly among man is an abomination to God.

Being sure that one is in the kingdom of God is an urgent,  even a pressing need for all who will come.

Jesus said,  “It is easier for heaven and earth to pass than one tittle of the law to fail.” One tittle of the law is a Hebrew letter the smallest of the Law of God, and Jesus tells us basically, that we can be sure and secure that all His word is truth, and will come to pass.
