God doesn't change, so yes. However, the Ten Commandments weren't given to save us; they were given to show us our need to be saved. As someone pointed out Christians are people, and therefore, imperfect just like the rest of the world's people. The Ten Commandments explain what God finds to be pleasing, and even the simplest one is something we can't manage to obey.

God doesn't say not to do things because He will punish us for doing them, He tells us not to do things because doing them produces results that harm us or others. The Ten Commandments are every bit as relevant today as the day God gave them to Moses, but obeying them does not impart Holiness. Only Jesus Christ redeems us from sin.

No. Thou shalt not kill or Thou shalt not commit adultery has nothing to do with today. That doesn't even happen anymore.
