First off, you need to be involved in Bible study within the body of your local church. Secondly, get a good commentary Bible from a solid Bible teacher. I have a John MacArthur NASB commentary Bible that is really good. Lastly, we can never know who God actually is if we don't read about who He is, as described in the Bible.
Enoch and Abraham never had a bible to read. Pretty sure theres other ways to get to know God. Of course you can just read about him though.
Oh, mercy. The primacy of scripture is a core doctrine of the Christian faith. Departure from Scripture is why there is so much error in guys like Joel Osteen, TD Jakes, Steven Furtick and others. The Bible describes exactly who God is and His character. Too many folks are trying to make Him up apart from what Scripture dictates. The Charismatic NAR and WOF movements are full of "worship" that is based much on experience but is much less concentrated around the Bible.
Someone else already mentioned 2 Timothy 3:16-17 - "All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, 17 that the man of God may be complete, equipped for every good work."
Emphasis on verse 17 about it completing man.
