Is it possible to prove/demonstrate the existence of God to an atheist (i.e. someone who doesn't accept the Bible as "proof")? If so, how can it be done effectively without using the Bible? If not, does that bother you, or are you comfortable with just saying it all comes down to "faith?" Is there "one" open-and-shut case for Christianity, or do we have multiple apologetic methods because there are multiple personalities and ways to persuade people? Since Christians believe by "faith," is trying to offer evidence (i.e. physical/rational) sinful? Thanks!
