Is unquenchable joy possible? Not entirely, but we can get glimpses of it here on earth by getting off of ourselves and giving thanks to God for the work He is doing in the ordinary circumstances of our lives. God is active in each one of our lives, and oftentimes we miss that. God works through even the hardest experiences in our lives specifically to help us grow, to help us be better people and to help make the world a better place. If we can trust in that (which, yes, is hard to do!) it creates a whole new freedom in us and around us.
