"Suddenly she had a completely new thought. The Declaration and the song came together in her mind, and she thought: God is America's king.

She thought: Americans won't obey any king on earth. Americans are free. That means they have to obey their own consciences. No king bosses Pa; he has to boss himself. Why (she thought), when I am a little older, Pa and Ma will stop telling me what to do, and there isn't anyone else who has the right to give me orders. I will have to make myself be good.

Then you have to keep the laws of God, for God's law is the only thing that gives you a right to be free."
