In her letter to Smith, Ellen White wrote of what is before the church: 3BIO 259.2
From that which the Lord has been pleased to show me there will arise just such ones all along and many more of them claiming to have new light, which is a side issue, an entering wedge. The widening will increase until there is a breach made between those who accept these views and those who believe the third angel's message. Just as soon as these new ideas are accepted, then there will be drawing away from those whom God has used in the work, for the minds begin to doubt and withdraw from the leaders because God has laid them aside and chosen more humble men to do His work. This is the only interpretation they can give to this matter, as the leaders do not see this important light.—Letter 20, 1884. 3BIO 259.3
In her testimony dealing with the Raymond matter, Ellen White sounded a solemn, startling warning: 3BIO 259.4
The enemy is preparing for his last campaign against the church. He has so concealed himself from view that many can hardly believe that he exists, much less can they be convinced of his amazing activity and power. They have to a great extent forgotten his past record; and when he makes another advance move, they will not recognize him as their enemy, that old serpent, but they will consider him a friend, one who is doing a good work.... 3BIO 259.5
Satan hopes to involve the remnant people of God in the general ruin that is coming upon the earth. As the coming of Christ draws nigh, he will be more determined and decisive in his efforts to overthrow them. Men and women will arise professing to have some new light or some new revelation whose tendency is to unsettle faith in the old landmarks. Their doctrines will not bear the test of God's word, yet souls will be deceived.—Testimonies for the Church, 5:294, 295. 3BIO 259.6
