Polarized Out Of Heaven

My friend Jaded CM wrote recently about rewards and heaven. He was saying that he didn't really believe in a material rewards system for kid's ministry. To this, someone responded that he must not believe in heaven. The funny thing is... Jaded CM is probably the most conservative person on our church staff... he definately believes in heaven. Our society has become so polarized. Whenever someone disagrees, people just throw names and labels around instead of engaging in true debate and conversation. In this particular case... a jump from rewards in the classroom to a belief about heaven. Whoa! And the thing I see is that it is often Christians that are doing much of the polarizing. What have we become? How can this be changed?
