I guess I don’t understand what you are saying. You either go by the Bible or you don’t. If Scriptures weren’t for us to understand, then why do they read them in church?
Of course we read out the Bible in Church; this is also where the meaning of it is explained to us.
Unfortunately, there are lots of man-made churches out there where the preaching doesn’t actually conform to what the Bible says - they just pick out a few verses (like that pamphlet,
The Romans Road), string them together like an
I Ching* prophecy, and come up with stuff that the Bible doesn’t actually say when you read it in whole sentences and whole paragraphs.
There is nothing in the Bible that even
remotely suggests that we can have the assurance of our salvation without being obedient to Christ’s commandments, or that we can think that no matter what we do in the future, our sins are in some way “pre-forgiven.”
I can know, if I were to die this minute, whether or not I would go to Heaven, but I cannot know that I will remain in this condition for the rest of my life. At some time in the future, I might reject Christ and set myself on the path to Hell. If I do that before I die, and if I don’t repent again before I die, then I will most certainly end up in Hell - the fact that I am dedicated to Christ at this particular moment in my life, and the fact that I would go to Heaven if I were to die right now, in no way “assures” me that I’ll go to Heaven in 40 years.
The only way someone could come up with that idea is by taking part of a section here, and part of a paragraph there, and sticking them together, even though in the original text, they are not even in the same
book, let alone in the same sentence.

I Ching is a game of prophecy in which random criteria are used to select sentences from a book. You then put the randomly-selected sentences together to make a prophecy about the future.
There are many people who treat the Bible like a game of
I Ching.
