Don’t Be Conformed to This World

In Romans 12:2, under the inspiration of the Holy Spirit, Paul instructed us, “Don’t be conformed to this world, but be transformed by the renewing of your mind, so that you may prove what is the good, well-pleasing, and perfect will of God.” What does he mean when he says to not be conformed to this world? What does he mean by being transformed by the renewing of our minds? Is he writing of a one-time event, or are we to continuously renew our minds? How does this affect the way we are to view and interact with the world around us?
