Contact a Local Church.
One of the easiest ways, and actually the very best way to obtain a free Bible is to call a local church. Most large churches have a surplus of "left behind" Bibles in their lost and found. My church has so many unclaimed Bibles that we ask a local prison outreach to come and distribute them to prisoners. Some churches will even give away a new Bible if you don't have one. Don't be shy! If you truly need a Bible, most Bible teaching churches will be happy to set you up.

Or pick a Gideons from a hotel room. Its free also. But make sure you read it o. Someone paid for it

You could also get a free Bible online. But however you get it make sure you read it and apply the things you learn to your daily life. Let ppl see the difference and don't just use it to argue on nairaland.
