Another non-LDS Apologist on the Importance of the Illumination of the Holy Spirit

By no means do I wish to disparage the work of the Holy Spirit in giving Christians discernment. Certainly all Christians must depend on the Holy Spirit to illuminate their minds that they may clearly see the difference between good and evil, truth and error. And many Christians who are ill-equipped to study doctrine in depth are remarkably discerning. (Robert M.
