What "balance" is or isn't is pretty subjective. I feel that I am (balanced) in my understanding of scripture but others would disagree.
I don't think that people tend to be extremists by nature. I think a lot of how we view the world and how we view and understand things including Scripture and living for God is based on example and teaching. Both at home and in the church.
I think I was raised in a pretty moderate environment - both at home and in the church too.
I think my bubble is pretty much in the middle.
LOL!
