Matthew 5:19-20

19 A person may choose not to obey a rule in God's Law. He may think it is the least important rule. He may also teach other people to think like that. Then God will call him the least important person in the kingdom of heaven. But a person may choose to obey all the rules in God's Law. And he may teach other people to obey them too. God will call that person great in the kingdom of heaven. 20 I tell you this. You must always do what is right. You must live in a way that is better than the teachers of God's Law and the Pharisees. You will never come into the kingdom of heaven if you do not do better than them.’

5:20The teachers of God's Law and the Pharisees thought that they obeyed all God's rules. But they did not truly love God.
