There something real there... or... at least seems real. Trouble is a Catholic, a JW, a Mormon, a Pentecostal, a Baptist etc. probably all think that waht they believe is real and believe they "know" the real Jesus. But their beliefs are different enough that they all can't be true. And I've seen a non-gift believing Christian get "slain" in the spirit and start talking in tongues and they completely changed. They thought they "knew" Jesus before that, but now, after getting baptized in the spirit, they really knew Jesus.
Then the next step, whether it getting saved or getting baptized in the spirit, they now read the NT and Bible in a way that compliments those beliefs.
But I just remembered another problem with the Christians that say they take the Bible literally... And that's Isaiah chapter seven. Verse 14 says all that stuff about a virgin (or young maiden) will give birth to a son, but what about the verses that come after that? The verses that tell us some more information about the boy. Things about him eating curds and by the time he gets old enough to know right from wrong the two enemy Kings of Judah will be dead.
If they want to take Isaiah literally, those verses need to apply to Jesus also. If not, then how is only verse 14 about Jesus and the rest of the verses aren't? But of course, that's not a problem. All a person has to do is ignore those kinds of details.
