Alcorn makes an analogy which I have heard before: that we are citizens of heaven and ambassadors to Earth. We have to live here on Earth and need to learn all of Earth's customs, etc. Yet, we are not to become like the citizens of Earth. We need to maintain the values and thought patterns of our true home, of heaven.
We are representatives of heaven here on Earth. Do I act like it? Not usually. God, give me the strength to represent heaven like I should!
