There is no such thing as a purely objective bible student. We all have different experiences that shape the way our brain processes information. We all have a tendency to analyze information in such a way that reaffirms our preexisting ideas and convictions. When we study an idea that we already disagree with, we usually approach it from the perspective of why it is wrong. When we study something we already agree with, we usually approach it from the perspective of why it is right.
For this reason, we all need to own up to the fact that we might believe certain ideas only because a belief was handed down to us. We might believe something is true simply because we’ve filtered the Bible through our beliefs.
So what do we do about it? We shouldn’t pretend that we’re immune from being biased towards certain beliefs. The honest thing to do is to acknowledge our own beliefs, and be aware of the tendency towards confirmation bias. Humility is the best friend of objectiveness. It doesn’t take humility to admit when we are right. It takes humility to admit when we are wrong.
In other words, the best way to avoid filtering the bible through our own beliefs is to develop the humility necessary to filter our own beliefs through the bible. We need to be self aware of the need to examine our own ideas just as critically as we would examine the ideas of others.
