The mind that becomes soiled in youth can never again be washed clean. I know this by my own experience, & to this day I cherish an unappeased bitterness against the unfaithful guardians of my young life, who not only permitted but compelled me to read an unexpurgated Bible through before I was 15 years old. None can do that and ever draw a clean sweet breath again on this side of the grave.

The Bible itself can be used for both good and evil. That doesn't mean it's flawed. It means that it is perfect.

For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms. Eph. 6:12 (NIV)

The bible divides mankind, god will decide our fate.

...it is a mistake to reduce every decision about Christian living to a "Heaven-or-Hell issue."For example, some ask if the Bible specifically says a certain action is a "sin" or will send them to "Hell." If not, they feel free to indulge in that action unreservedly and ignore any scriptural principles involved. But this approach is legalistic, which means living by rules or basing salvation on works. It treats the Bible as a law book, focusing on the letter and looking for loopholes.By contrast, the Bible tells us that we are saved by grace through faith, not by our works (Ephesians 2:8-9). Grace teaches us how to live righteously, and faith leads us into obedience. (See Titus 2:11-12; Romans1:5; Hebrews 11:7-8.)

If God were willing to sell His grace, we would accept it more quickly and gladly than when He offers it for nothing.
