I think you are confused.
There is no point whatsoever, and certainly not a moral one, on attempting to guide myself by scripture attributed to a deity.
And even were I to take it for granted that somehow there is... the Christian Bible hardly qualifies, or even attempts to.
Edited to add: To elaborate, morality is not obedience to rules. The proper name for that is indeed obedience.
Morality is something else entirely, something far more dynamic and ambitious. It is an emergent property of the convergence of the ability to predict the likely results of behavior and the ability to perceive and empathise with situations of pleasure and pain, gain and loss.
It is IMO objective, but by no means delimitable by mere scripture. Quite on the contrary, true morality can only exist over the background of an active, rational being capable of perceiving existence and making value judgements accordingly.
