The Elect

I was thinking about just how many of those that profess faith in Christ are truly saved. I see so many cultural Christians and false converts it sort of depresses me. I recall Scripture indicating that narrow is the way to salvation and few who take it. And even Jonathan Edwards believed that only about 5% of his congregation were truly saved, and that was during a time of the Great Awakening and when people were much more churched than they are now. Is it possible that 95% of those who profess faith in Christ are actually lost and will be the ones who the Lord says "Depart from me." What do you think?
