I could be reaching here, but I'd like to expose a potentially trendy heresy before it becomes a popular one. This is my theory: As is the case with many breakout theological trends, the prosperity gospel is developing an antithetical counterpart which is equally destructive and even more deceptive than the original. I'm calling it the false poverty gospel and it goes like this:
"Because I am saved, all of my treasure is in heaven, and I therefore live like a vagrant. If anyone questions whether I love Jesus, I need only point to my lack of worldly goods as unquestionable proof that I do. Furthermore, anyone who keeps any worldly goods is clearly a rich young ruler who has walked away from Christ."
I have worded this in such a way that it sounds ridiculous, but that's the point. Of course it's ridiculous when you say it out loud. And yet I see this attitude expressed non-verbally on a consistent basis nowadays. I also see people who have had much taken away from them due to economic difficulties beyond their control become quite self-righteous about their new found simplicity. Claiming poverty as proof of God's love is no less ridiculous than claiming prosperity as proof of God's love.
Poverty is not fruit of the Spirit. It is a condition which can allow us to have faith in the provision of God through others. Prosperity is not a fruit of the Spirit. It is a condition which can allow others to have faith in the provision of God through us. We are justified by grace through faith in the prosperous poverty and impoverished prosperity of Christ.
