If you currently don't believe in God and were offered the chance to believe in God for a day would you accept the opportunity? I'm not talking about the 'just open your heart' bullshit. I'm talking about if someone were to be able to neurologically rewire your brain for a day so that you perceive things the same way a believer would. At the end of the day you'll be asked whether you want to remain in belief or be rewired back. You'll remember the experience regardless whether you choose to be rewired back.
Will you accept the offer? Are you afraid that you may not want to be rewired back once you believe in God?
