This is the myth: Non-believers know deep down they're being drawn towards (the evangelical) God; witness to them and pray for them enough, and eventually they will be born again. For the believer, even showing a hint of interest in Christianity is evidence of this almost irresistible urge to convert.
I had this notion once, too. My attitude toward non-believers was: How could they not know how much they need this? In my mind, "unsaved" family and friends were empty, and they knew it. If they were honest with themselves, they knew the gospel was true, or at least they felt a strange compulsion to find out more. For this reason, I lived most of my born-again Christian life thinking that the conversion of others was not only possible but likely.
This conception leads to awkward conversations like the one I had yesterday with an old college friend. Said friend knows that I am now openly gay, theologically and socially liberal, and about as far from evangelical as you can get. The occasion was my mention that I had read a sermon by a mutual college friend online. He replied that he was glad I was "getting back into it," and I quickly clarified that by no means was this a sign I was returning to anything--or even thinking about it. I was just reading a sermon by someone I knew because it piqued my interest.
"LIAR." (The block capitals were his. This was an internet messenger conversation. He was being a bit tongue-in-cheek, sure, but his point was serious.)
I could hear the cogs whirring as we continued the conversation. Praise God. The Holy Spirit is working on Dave. He won't admit it, but he's being drawn back into the fold.
I explained it as best I could like this: You suggesting there's a realistic chance I'll return to evangelical Christianity is like me suggesting you're going to become a Muslim or start a new career as an accountant. The thought is alien to me.
You may as well tell the average Joe they're going to move to Africa and live with lions for the rest of their lives. Keep giving them the safari pamphlets, but unless they already have Mowgliesque inclinations toward chumminess with feral cats, they're probably going to stick with their day job and their reasonably priced semi-detached house in Manchester.
Some people do have that feeling of something missing and get that irresistible urge to convert to evangelical Christianity, no doubt. Most people, however, don't.
