We've all had those throw-in-the-towel days, the kind that make you want to give it all up. In Amy's song, she sees two letters. The first is from a friend reminding her of the ultimate goal--heaven. The second is from God, with the same reminder, that heaven is our home, and we're only here to learn to serve Him. She bemoans how often she forgets this important truth, but isn't that how it is for all of us! Oldie, but a goodie.
