These trials are God working in us to complete the good work He has begun.  What does it mean to count it all joy in these trials?  It means that our love abounds rather than growing cold when the trials come, it means approving things that are excellent rather than letting our ego get in the way, it means being sincere and without offense rather than becoming political and vengeful, it means being filled with the fruits of righteousness rather than a long list of petty grievances.  It means being able to see that Paul being arrested by a corrupt Roman government and imprisoned actually worked out to the furtherance of the gospel, made others more bold to speak the gospel, and the gospel is being preached more than ever before.  Paul tells us in the book of Philippians how we can count it all joy.
