What did the Giver mean when he told Jonas that honor is not the same as power?

Honor is earned respect or esteem, which is given. You can, for example, honor God, even though God has no physical power over you. Power, on the other hand, is force. You may not honor your boss, but he has power over you and can terminate your employment, transfer you to the ends of the earth, or do whatever he chooses as long as you remain in his employ.
