The intention is not wrong (after all, it's the intention that counts!), but we obviously do not all read the Bible the same way (yet everyone claims the same Holy Spirit as the Guide).
I think it seems plain that we neither possess the language nor mental capacity to fully understand God; nor do we have the knowledge and the feel for the history, the culture and the language of the times when different books were written.
Then neither does the Pope, the Cardinals, the elders, the Bishops, etc. If we can't trust the Holy Spirit, then we are lost.
I look for the simplest meaning first. Then, if that is not satisfactory, I look to others who have knowledge and seek their input. I test it all to scripture. Scripture has to be the final arbitor in all things. It IS the Word of God.
Just as the Holy Spirit who knows our hear speaks to the Father with inexplicable moanings, He also reveals to each believer all elements of faith and belief which we receive.
He paces us, knowing exactly the best way to provide for us as had been predetermined from eternity past.
There might be a gradation of fellowship in the environments surrounding us. We know that it isn't what goes into a man that defiles him, but what comes out of him.
We might test things by worldly standards. I could go into a strip tease bar and ask the waitresses for advice, but will likely be more influenced by corruption than by holiness.
Using Scripture as a guide when discerning issues is an outstanding source of discernment, provided one remains filled with the Holy SPirit in all things. For this reason I see nothing wrong with 'sola scriptura' as a practical policy. This doesn't exclude other methods God might employ to effect His plan or will, but it is an outstanding policy, sepecially since no previous generation prior to the Church Age has available to them what God has provided us today in knowing His will so explicitly via Bible doctrine.
In a nutshell, none of us have any capacity to understand God separate from the enabling ministry of God the Holy Spirit. His ministry though is more than a soulish exercise. He supernaturally reveals things to us in our human spirit which through faith in Christ we are able to perceive.
