Thoughts on I Peter 4: Suffer for the right reasons

For Christians, not all suffering is created equal.  I used to be involved with prison ministry and I was always surprised when I heard some prison ministers, and more often the prisoners themselves, argue that they were suffering for Jesus.  I suppose it is possible that they were put in prison for serving God, but I sort of doubt it.  In chapter four, Peter clarifies, "But let none of you suffer as a murderer, or thief, or criminal, or troublemaker." Suffering is only rewarded by God when it is done for being Godly.  And when you are suffering for being Godly, you can trust God to reward you when the time comes.
