'Submitting' in the Bible

The 70 disciples came back and joyously reported, "Lord, even the demons are submitting to us in your name!"

However, stop rejoicing because the spirits are submitting to you. Instead, rejoice because your names are written in heaven."

If you have died with the Messiah to the basic principles of the world, why are you submitting to its decrees as though you still lived in the world?
