"It is Satan's plan to weaken the faith of God's people in the Testimonies. Next follows skepticism in regard to the vital points of our faith, the pillars of our position, then doubt as to the Holy Scriptures, and then the downward march to perdition. When the Testimonies, which were once believed, are doubted and given up, Satan knows the deceived ones will not stop at this; and he redoubles his efforts till he launches them into open rebellion, which becomes incurable and ends in destruction."--4T 211
