Chapter 3 of The Great Hope warns about the subtle and dangerous deceptions Satan uses to lead people away from truth. While many expect temptation to look evil and obvious, the real danger lies in how spiritual error is often disguised in beauty, culture, or even religion. The chapter highlights how spiritualism and false teachings are growing more accepted—even among Christians—fulfilling prophecy and weakening discernment in the last days. This is a wake-up call for believers to know truth for themselves and stay anchored in Scripture.
