If you don't see a danger ahead, it's unlikely you'll take the necessary precautions. Far to many fall into a trap on their spiritual journey that is described in the opening chapter of the book of Revelation, and that can derail them because their experience doesn't line up with their expectations. Be forewarned and forearmed, and less likely to be derailed by the realities of life in the Kingdom when you get a realistic expectation what it entails.
