Adventist Alternative: Public Evangelist/Author, Dr Pieter Barkhuizen proposes a challenge to the General Conference of Seventh-day Adventists to dialogue with him and supporters of the protest-organization, Good Hope Institute, the REASONS WHY Adventists are leaving the church in droves. A trained Systematic Theologian, Dr Barkhuizen points out that the unBiblical doctrine of a pre-advent, Heavenly, Investigative Judgment lies at the core of his challenge.
