I doubt you or I are one of the two who could understand...

...but the post linked is worth reading.

What we can really be certain about in life is very, very little, and it seems with the passing of time it becomes less and less. Certainty as a sentiment is not the test of faith, deeds are. It is not that we have to lie about our difficulties, our opinions, and our failures in order to believe. The key is to accept them and to keep going. To keep going to Orthros at four in the morning, to keep going to Mass on Sunday even if everything is not perfect, and to keep striving to love even if you know you will fail is how we will make it through this vale of tears. There is no certainty in this: there is only duty and resolve, and that duty and resolve must come from the heart.
