Is it dangerous to take someone else's word for something we know little about? If so, how do we ever learn anything new?
When it comes to scripture, there are literally thousands of teachings, hundreds of thousands of books written by people smarter than me, and so many opinions out there that they could never be documented.
As children, we take what our parents teach us about everything, even the Bible. In school, we believe what we are taught and read in our textbooks, which used to be ok, now a very dangerous thing to do, as some are full of false teachings about the origin of man, and the existence of God.
So what's a person to do? As we age, we become able to study, and find out for ourselves what is truth. We no longer depend on what mom and dad or anybody else says.
When it comes to the bible, that's truer than ever. Maybe what the preacher says, a book says or mom and dad says is true. MAYBE IT'S NOT!
If we don't look and learn for ourselves, how will we ever know? The very encouragement to do so is in fact stated in scripture, “Study to show thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth.” 2 Timothy 2:15 KJVA
We are sort of a 'prove it' society about most things, and doctrine should be no different. If scripture doesn't prove what we believe, we need to reconsider our beliefs. And if what someone is teaching can't be proven by scripture, we need to reject it, and find out what really is true. Our eternal destiny depends on it!
