Trying to witness to an atheist and no matter what I say, how I try to use logic and reasoning, or even recommend books with plenty of defenses of Christianity, or even websites with defenses the atheist become illogical and base their rejection of christian on "bad experiences" or "bad people." I would then respond and ask them how experience is objective fact when truly it is very subjective. Or how a bad Christian can bring down an entire viewpoint? I mean how would I know the person has not had a run in with a Catholic, cult member, or progressive liberal Christian? All too often do these people get confused with real Christians when they are not, but simply false converts. As one who does lots of street evangelism I am finding out that 99.9% of atheists are of this way, and absolutely refuse to use logic and reasoning and look at Christianity differently. Do you know why? Because unless God grants repentance and regeneration which proceeds faith they can never come to faith. God knows His elect and has called them to salvation. For them books on evidences of Christianity are valuable. To them to Bible is pure gold. But to others the Bible and everything is worthless and they will never consider it.
