A while back I wrote a post about how we all....ALL of us....choose what parts of scripture to embrace and what parts of scripture to ignore. There are many contradictions in the Bible...which is why there are thousands of denominations and belief systems within Christianity. You can support just about anything with scripture.
Steve McVey (in a post I read "at the gym") said it this way:
It's as if when we read the Bible, the verses that support what we already believe seem to be highlighted or italicized while the verses that might disprove and dismantle our current belief are skimmed over, almost as if they are invisible. Our bias serves to reinforce our view by causing confirming evidence to jump out at us while blinding us to any evidence that might threaten our current view.
This isn't always such a good thing because it can keep us in belief systems that are flawed...even dangerous. It is the subconscious version of sticking our fingers in our ears and doing the la-la-la-la-la-la-la, I don't hear you" chant. We simply can't---or won't look farther than our preconceived beliefs. Or sometimes, if we do, we grab hold of the new with the same gusto we clung to the old.....
As Ashleigh Brilliant says:
My opinions may have changed, but not the fact that I am right.
We have to keep an open mind....but not so open our brains fall out. Been there, done that.
