19 Whoever, then should break one of the least of these commandments and should teach men to do so, shall be called least in the Kingdom of Heaven; but whoever shall practice and teach them will be called great in the Kingdom of Heaven.
For the Jews at the time of Jesus there was the moral Law and the ceremonial Law. The ceremonial Law laid down what was required for the sacrifices and offerings that were to be made by the priests and people, and this was carried out in the temple in Jerusalem.
The moral Law was different, and contained the Ten Commandments. This dealt with how everyone should live in their relationship with God and also in their relationships with one another.
It was this moral Law that Jesus quoted from in Matthew 22.36-40:
36 “Teacher, which is the most important commandment in the law of Moses?”
37 Jesus replied, “‘You must love the Lord your God with all your heart, all your soul, and all your mind.’
38 This is the first and greatest commandment.
39 A second is equally important: ‘Love your neighbour as yourself.’
40 The entire law and all the demands of the prophets are based on these two commandments.”
Jesus was telling His listeners that the lifestyle of the people of God must continue to be built upon our relationship with God.
Except for the command not to murder, steal, or bear false testimony against a neighbour Western society has largely abandoned the Commands of God. Consequently our society has moved further and further away from God. The end result is that people and society forfeit being part of the Kingdom of God.
Paul wrote to the Galatians about this:
19 When you follow the desires of your sinful nature, the results are very clear: sexual immorality, impurity, lustful pleasures,
20 idolatry, sorcery, hostility, quarrelling, jealousy, outbursts of anger, selfish ambition, dissension, division,
21 envy, drunkenness, wild parties, and other sins like these. Let me tell you again, as I have before, that anyone living that sort of life will not inherit the Kingdom of God – Galatians 5.19-21 (NLT).
God provided humanity with commands that are for our good, they bring us His blessing. To ignore His commands is to miss out on His goodness and blessing.
