Jesus taught that it is important to obey all of God’s commandments.

Matthew 5:17-20

17 “I came to earth, not to annul the laws that God gave Moses or what the prophets [MTY] wrote. Instead, I came to cause to happen what the authors of those books predicted would happen. So do not think any longer that I have come to earth in order that I might annul what they wrote. 18 Keep this in mind: Every point of those laws, including those points that seem least important, and even the smallest details of the laws [MTY] will surely be in effect [HYP, LIT] until the heavens and the earth disappear and until all that God told their authors to write happens. 19 Since all God’s laws are important, if anyone disobeys any of those commandments, even if it would be one of the least important ones, and if that person teaches people to disobey any of those commandments, it will be said {God will say} that that person is the least important of those in the place where [EUP] God rules. But those who obey those commandments and teach other people to obey them, it will be said {God will say} that they are very important among those that God rules. 20 Keep this in mind: You assume that the Pharisees and the men who teach our laws faithfully obey what God commands. But if you do not obey those laws better than they obey them, you will by no means enter the place where God rules.”
