You got to be kidding me, right?
It's pretty obvious. Look back on your life. Do you not see God trying to let you know what to do? Like most of us, you didn't listen at the time, but in retrospect, you see it now.
Look at a tree, or a flower, or a sunset, and you see God.
No book needed. It's right there in front of you, everyday.
Perhaps you need guidance from some 2000 year old book, or from self-professed expert guides (priests, etc). I don't.
I am happy to see that you see God in your life and in the simple things - that is so very true and is around us daily if we just look.
But don't let man turn you against the Bible as that is God's inspired word. If we did not have His word we would have to get instruction on what to do to follow Him and please Him by hearing the word through others.
How would you know about Jesus and why He was sent without God telling us and laying out what He expects of man.
Man can ignore or misinterpret the "feelings" of God letting us know far too easily based on what we want. An example - your comments above about you liking the idea of Jesus having children and a family, that it shows something about sex (I can't flip back to read your comments because everytime I flip out of my post to check on something, I lose my post. This is the third version I've written this time).
Suppose a man just loved molesting children. He could easily justify his actions by telling himself that Jesus loved children too, and then getting a nice comfortable feeling that yes, Jesus would feel molesting children was acceptable. So - although we do often feel we know what God expects through our relationship, out of respect for God, we should at least honor his inspired word to learn what God thinks.
And in the New Testament God made a new covenant with man. He sent His Son, Jesus, to live as a man and be tempted as we are. And Jesus was to spread God's word teaching through the land. Then Jesus was to be cruxified on the cross to die for the sins of man. Jesus paid the price for our sins.
All we have to do to receive this eternal life is to
-confess our belief that Jesus is the Son of God
-repent of our prior sins and be baptised for the remission of those prior sins and we will be saved.
We then are added to Christ's church and Christ will intercede for us with God. And we follow God through our lives.
Here is the website of John Clayton-a former atheist who set out to prove the Bible was inconsistent with science and full of flaws. He was an science teacher and avidly radical about the Bible. Yet, he could find no inconsistency with science. He became a Christian and set out to find a church that taught what the Bible taught. Very interesting - his seminar information is there on the website so that it can be read.
