Book excerpt: Ellen White called Christ's ministry in the heavenly sanctuary "the foundation of our faith" (Evangelism, page 221) and said if the people of God don't understand the investigative judgment, "it will be impossible for them to exercise the faith which is essential at this time." (Great Controversy, p 488). But critics of this doctrine say it can't be supported from Scripture, and they claim that no one who believes it can have the assurance of salvation. Popular author Marvin Moore has examined the objections of the critics and the best thinking of dedicated Adventist scholars. In this book, he aims to help the readers understand this foundational doctrine and gain its spiritual benefits - based solely on the evidence from Scripture.
