In short, he spoke of the importance of obedience. This isn't mindless obedience in an attempt to divest ourselves of responsibility. Rather, it is obedience to God and His precepts that we should love one another. While it is important to question orders, especially when those orders conflict with our personal morals or society's ethics, so often we question as a way to avoid action. Obedience requires action on our parts, action which we so often procrastinate. Sure, we talk a good talk, but do we actually take steps to make the world a better place (this is certainly directed at myself).
However, rather than spend time playing the blame (including self-blame) game, he also said that we need to remember that it's okay to be flawed. Our own parents, teachers, and priests were flawed, but we still learned from them. So to will our children and others learn from us. Being flawed does not mean that we don't bring something of value. In fact, our flaws can often be the connection we need to the other flawed beings around us so that we can recognize each other and work together to overcome our flaws.
... including the flaw of waiting too long to work on two papers that were due tonight.
