Writing some years later concerning apostasies and the involvements of those who lost their way, Ellen White pointed out five natural steps: 1BIO 315.4
“It is Satan's plan to weaken the faith of God's people in the Testimonies.” “Satan knows how to make his attacks. He works upon minds to excite jealousy and dissatisfaction toward those at the head of the work. The gifts are next questioned; then, of course, they have but little weight, and instruction given through vision is disregarded.” “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. 1BIO 315.5
“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.”—Testimonies for the Church, 5:672. 1BIO 315.6
