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.
When you live life from your center, you operate from the indwelling spirit outwards into the visible world, like the spokes of a wheel, radiating God's love, wisdom and power. This is what is meant by being in the world but not of it. You remain calm in a crisis. You carry this calmness with you through the ordinary activities of the day, even when things go wrong... Centered in peace, you experience JOY... This is the culmination of growth in being. What you ARE, far more than what you say or do, will be the witness of your faith.
