Yes. I've picked up several interesting things from the book so far.
One is that Islam has great appeal to people who want strict rules that they can obey unquestioningly. Where Christianity and Judaism both expect people to question and discuss and thereby grow spiritually, Islam requires its adherents to accept and obey without question.
The authors rightly point out that a recent danger within Christianity is the feel-good liberal mainstream churches that levy no rules or requirements on their members. Many people drift away from their religion simply because there's no structure, right vs. wrong, etc. The authors cited quotes from American converts to Islam who praised the clear, unchanging, strict rules of Muslim life, which made them feel safe and secure.
That really rang true to me. I attend an evangelical Christian church (Southern Baptist) because it requires me to question and discuss and learn, but still has a core of biblical tenets which you must accept to be a member.
There are a lot of fascinating comparisons in the Caner book.
All very interresting and true. And yes the warm fuzzy liberal "Churches" are definitely a pet peeve of mine. Politicize the Bible, take out the parts they don't like, and accept every queer and immoral person sleeping around and shacking up and just remove morality from the Bible and rewrite what's inconvenient to their primary loyalty; liberal political social lack of values and ethics and morals. Those are the Christians who vote Democrats. Ones who's Christianity is a joke, and is second to their Democrat loyalty which is first. I know people like that and they disgust me. Any Christian who claims to be such, and votes Democrat all the time militantly, being abusive of people who don't vote Democrat, despite the total Democrat opposition to Christian values, they're a joke to me and their supposed "Christianity" is a joke and they'r hypocrites. They are Democrats first and Christians and Americans second, and that is not acceptable.
