The Bible is just a bare bones dating-and-approach protocol with some philosophy thrown in.
More likely than it "not working for you" is you just simply not working, period. Your head is probably in the wrong space. Probably have some self-limiting beliefs and fears stored up, these fears being triggered in social interactions is what kills the fun.
You're not in state enough, if the Bible stuff doesnt work. If you're not in state, nothing really works very well. Conversely, if you're REALLY in state, you can throw away the rulebook and just go for it and have success (others have said). So the question is, why are you not in state?
I would conclude that its inner game thats holding you back.
