What I've seen on my rounds is that if you are lucky enough to have the opportunity to reflect at the end of a life, then love is revealed as the great currency. It's the thing. The treasury. It's what mattered...
How well did I love? whom did I love?, and how was love central to the life that I made for myself?
...When the lots are counted, when we are gathered in, we will find that it was love that mattered. Love expressed, given, received, fought for. So for those of us fighting right now, I say; keep going. As a culture, as an individual, believe in the full life that is your bequeathed inheritance, not the subterranean half-life that terror and impoverished minded bullies will try and spike your wine with. You are too good for that.
What do we do with suffering? As far as I can see, we have two choices — we either transform our suffering into something else, or we hold on to it, and eventually pass it on.
In order to transform our pain, we must acknowledge that all people suffer. By understanding that suffering is the universal unifying force, we can see people more compassionately, and this goes some way toward helping us forgive the world and ourselves. By acting compassionately, we reduce the world's net suffering and defiantly rehabilitate the world. It is an alchemical act that transforms pain into beauty. This is good. This is beautiful.
To not transform our suffering and instead transmit our pain to others,...compounds the world's suffering. Most sin is simply one person's suffering passed on to another. This is not good. This is not beautiful.
The utility of suffering, then, is the opportunity it affords us to become better human beings. It is the engine of our redemption.
