Here's a scary thought: What if God called you to give beyond your comfort level? Would you be afraid? Would you try to explain it away or dismiss it as impractical? And in the process, would you miss out on a harvest opportunity for which God had explicitly prospered you in the first place?
Real people are actively trying to live like fake people, so real people are no less fake. Every comparison becomes impractical. This is why the impractical has become totally acceptable; impracticality almost seems cool.
