Is the Law of Moses Valid for today?

[soliloquy]

Well, I believe that obvious rules, like the Ten Commandments, are something you still follow, but when Jesus came to earth, it meant that we no longer had to do all the sacrifice and rituals required since He came to be the final sacrifice for our sin. So lots of things in the Law of Moses, like no eating pork or sacrificing animals, are no longer needed in order to be saved.

The sacrifices and rituals were never for the gentiles. They were for the Jewish people. We are not required to keep them. Any "rule" we need to keep was repeated in the New Testament. We also have to be careful not to fall into a state of legalism because that can be a stumbling block for others.
