Education is a means, not an end. We don't enroll in formal education ad nauseam as a way of escaping life. Rather, we educate ourselves in order to become equipped to respond wisely to God's calling.
Justice doesn't have a finish line, and neither does education. We never reach a point where we cannot learn, where ceasing to learn would make us, or the world, better. It takes perseverance to walk the road of justice, and we cannot know where or when--or if--it will end for us.
