Let's say you've grown up in a country that - somehow - has shielded you completely from any knowledge of the Bible and its God and history.
All your life you've believed in the four legged, three headed, four winged Borlifingus (of course, the arms, legs etc. are just representations of It's spiritual properties). You and your ancestors have prayed to your God, and It has answered, many times. You also have anecdotal evidence of Its existence.
And here suddenly along comes a Bible believer wanting to convert you, and tells you that the God you've believed in all your life and your ancestors all believed in, is false - doesn't exist.
-Let's say you're not going to just take it by what this preacher is telling you; you need some hands-on evidence.
What evidence that the Bible is true could the preacher show you, for you to convert?
Examples, please.
