Also OMYA, Jesus put all the commandments of "the law and the prophets" into 2 commandments (Matthew 22:37-40):
1) You should love God with all your heart , mind, and soul.
2) You should love your neighbor as you love yourself.
Also, since you think we should follow ALL of the Old Testament laws, then I hope you do not wear cotton and a different fabric on your body at the sametime. Also, I hope you don't light a fire on a Sabbath (from your stove, put on a TV or compter, drive a car, anything that takes up energy), because according to the Old Testament law, you should be stoned to death for that. Finally, do you give sacrifices? Would God punish me for not giving Him a sacrifice when I'm in NYC? There aren't that much lambs walking in the streets of NYC, I'll tell you that. Jesus was the sacrifice, that is why we don't have to kill animals anymore and bring them to the alter. Another reason that proves Jesus died and ressurected.
