There is a difference between self-inflicted "suffering," and suffering for the sake of the Gospel. You can be wealthy and be persecuted and put to death for the Gospel just as easily as a poor person in certain countries where there is heavy persecution. That kind of suffering doesn't take worldly standing into account whatsoever, so why would we twist it around and say that it does?
People who choose to give away what they have and live a far more modest lifestyle by choice so they can give more, aren't suffering. Well, they shouldn't be. Because it is more blessed to give than to receive, so whoever lives that way, should be just dandy.
Even so, come Lord Jesus!
