Matthew 5:19-20

19 So then, whoever disobeys even the least important of the commandments and teaches others to do the same, will be least in the Kingdom of heaven. On the other hand, whoever obeys the Law and teaches others to do the same, will be great in the Kingdom of heaven.

20 I tell you, then, that you will be able to enter the Kingdom of heaven only if you are more faithful than the teachers of the Law and the Pharisees in doing what God requires.
