Let's just reverse your conjecture so maybe you can see how shallow it is. What you are in effect saying is that you couldn't and wouldn't know TRUTH without your written bible to tell you. You must not even be saved. Isn't the Spirit of TRUTH supposed to live inside you after salvation and guide you into all TRUTH,or did you just think that meant He would tell you to read your bible more?
You are absolutely correct. Without the Bible I would be one bad son of bitch. Bank it. My wicked heart would twist shet up bad. My church would look like it was managed by Kid Rock, with ladies in bikinis collecting the tithe, because after all, it would bring in a large crowd and increase the tithing. Meanwhile, back at your church with a gay pastor..........
Then,I would say you have sadly placed all your faith-trust in a book of rules,rather than in the living God.
