The bible "allows" murder in the name of Yhwh, it allows for slavery and forced mariage/rape, and various other disgusting stuff (old testament) even the new testmaent has a lot of disgusting stuff like slavery, or even women being inferior and not beign allowed to speak up unless their man allow it (in chruch for example, corinthian), not even counting that it is "You shall not covet your neighbor's wife" and not , say , husband or significant other.
Furthermore the moral code do not come from bible or whatever, they were there before (ex. Amurabi code) and even before as soona s we were socially grouped, they are a Necessity for a stable society or group. Heck charity is even one of those. In small group you will be far more likely to help somebody not related to you, charity is only an extension of that, and is practised by non religious.
The bottom line is that the bible bring nothing new or special to the morality of its reader And as somebody said (was it hitchens) "show me any moral act which are practised by religious people and *ENEVER* practiced by any Atheist whatsoever". You won't find ANY such act. You are as moral as you as human are, and religion don't make you more or less moral. You will simply recognize YOUR morality INTO the religion.
