"When faith and hope fail, as they do sometimes, we must try charity, which is love in action. We must speculate no more on our duty, but simply do it. When we have done it, however blindly, perhaps Heaven will show us why"

This quote talks to the importance of acting in the face of difficulty. When faith and hope stop working, it can be challenging to know what to do. Nevertheless, Mulock motivates us to take action in the kind of charity, or love in action. She recommends that we should not hypothesize on our responsibility, but simply do it. Even if we do not understand why we are doing something, Mulock believes that if we do something about it, Heaven will eventually reveal us why. This quote encourages us to take action even when we are uncertain, and to trust that our actions will be rewarded in the end. It is a pointer that even when faith and hope stop working, we can still make a distinction through our actions.
