In today's first reading, St. Paul teaches the Corinthians about the Divine plan for passing things round:
For as Christ's sufferings overflow to us, so through Christ does our encouragement also overflow.
If we are afflicted, it is for your encouragement and salvation;
if we are encouraged, it is for your encouragement, which enables you to endure the same sufferings that we suffer.
To keep either our sufferings or our encouragement to ourselves is to treat ourselves as the final end of God's saving action in the world. And the final end of God's saving action in the world is quite a bit more than any of us.
