I think the thing to remember is that Paul was not just finding solace and joy in his faith at this time. He was finding it in people. Indeed he thanks god for the Phillipians at the start.
Of course god is there when we suffer, but god is there anyway. We do not need suffering to find god. Nor is it difficult to say "god I am suffering, please help me". What is difficult is saying the same thing to another person. And yet the quickest and most effective way to alleviate suffering is to reach out to people.
So why is it difficult to do this? Asking for help from people involves admitting our mistakes and weaknesses. It involves swallowing our pride. It is a time for reflecting on our failings and the barriers we construct to keep people out. All of this can bring us closer to god, ourselves and others.
The Buddha said that Life is Suffering. I agree. The hard times in my life have made me smarter, stronger, kinder and more understanding. They have also made me more appreciative of the good times. They have given me the kick up the arse that I have needed to make the big, scary changes that will ultimately benefit me and those around me.
During Holy Week, when I contemplate Christ's suffering, i find myself thinking of all the people over the world who are tortured, imprisoned and killed because of their beliefs. I think of the pain that is felt by their friends and family and most poignantly, their mothers. I come away re-energized in my efforts to do something.
Anyway, I don't think that people have to suffer to find god. God is there anyway. I think that life is suffering, there can be no meaningful life or love without suffering, but it is in the alleviation of suffering that we become better and closer to god, people and get to know ourselves.
I hope this makes some sense to Zulu.
