The other also wanted a pony but doubted whether they would ever get one. Christmas morning rolled around and there was a big box waiting for them. The pessimist started opening the box first, and saw that it was filled with straw and he began to dig down into the straw but only found something that looked like mature. That is wishing everything is going to turn out alright, that you will get what you really want, and that everything will work out for the best. There is a difference between optimism and hope although we use those terms interchangeably sometimes.
Hope goes beyond best wishes.
It does not depend on the circumstances of our lives. I believe that the writer of Revelation was not giving people optimism but was giving people hope. He was not saying that everything is going to turn out alright in your lives, that you are going to get what you want, things will be better tomorrow. Therein lies true hope. Our hope is in the person and presence of God.
