well...1/2 truths can draw people in. the stuff one likes about the truth, plus stuff you just...want to hear. something like that. or some biblical truths, minus the hard teachings, or...on and on it goes.
i think one can get hooked on religion. any religion. gives social life, meaning, identity, a place to park your shiny new suv....why not?!?!
if the calvinists are correct, then in 21st century america...2 out of 3 church goers are -false conversions- or at least...lots of people have yet to be genuinely regenerated by The Holy Ghost. something like that, anyway.
or maybe its lack of discple-ing, false doctrine floating around...i dont know. i lean towards TULIP, but that's just me. many are called, few are chosen. wheat+the tares. broad road, narrow way.
