Doesn't every Christian think that his particular faith is the truly correct one?
I would agree. But I would also add that when scripture states things like, "Man's steps are ordained by the Lord...", the text is rather clear. Rather than harmonize the verse with others like Augustine, people either shrug their shoulders and say it's a mystery or they'll say it doesn't mean what it states. There is no critical thinking.
Today we see too many people trying to wiggle their way around scripture. We have reach such a point that homosexual "Christians" will simply say that God is love and the scriptures really don't mean what they say. And many simply nod their heads and says we all have a different view on scripture.
