Ok, so lets have a look at Romans 1:18-32:
18 The wrath of God is being revealed from heaven against all the godlessness and wickedness of people, who suppress the truth by their wickedness, 19 since what may be known about God is plain to them, because God has made it plain to them. 20 For since the creation of the world God’s invisible qualitieshis eternal power and divine naturehave been clearly seen, being understood from what has been made, so that people are without excuse. Blah, blah, yada, yada ...
Hmm, so the Jesus witness is expecting to convince us that the Bible is right because it says so in the Bible.
This is one of the most fascinating things about the Jesus devout: they just can't fathom that the Bible has no meaning to a non-believer.
Infidel: "I don't believe in God and accordingly don't believe any of the God stuff in the Bible. In my opinion the Bible is just a tainted history book mixed up with a huge load of mythology."
Faithful: "But the Bible says that God exists, so it has to be true, I mean, come on, it's the Bible."
Infidel: "You don't seem to understand. I don't believe what the Bible says, the same as I don't believe in the Greek pantheon, Babylonian mythology, the Aztec gods, etc."
Faithful: "In that case the Bible says you're doomed to burn in Hell. Is that what you want?"
Infidel: "You just don't get it, do you?"
