To the law and to the testimony: if they speak not according to this word, it is because there is no light in them. Isaiah 8:20. Mar 167.1
The miracle-working power manifested through spiritualism will exert its influence against those who choose to obey God rather than men. Communications from the spirits will declare that God has sent them to convince the rejecters of Sunday of their error, affirming that the laws of the land should be obeyed as the law of God. They will lament the great wickedness in the world and second the testimony of religious teachers that the degraded state of morals is caused by the desecration of Sunday. Great will be the indignation excited against all who refuse to accept their testimony.21The Great Controversy, 590, 591. Mar 167.2
Those who oppose the teachings of spiritualism are assailing, not men alone, but Satan and his angels. They have entered upon a contest against principalities and powers and wicked spirits in high places. Satan will not yield one inch of ground except as he is driven back by the power of heavenly messengers. The people of God should be able to meet him, as did our Saviour, with the words: “It is written.” Satan can quote Scripture now as in the days of Christ, and he will pervert its teachings to sustain his delusions. Those who would stand in this time of peril must understand for themselves the testimony of the Scriptures. Mar 167.3
Many will be confronted by the spirits of devils personating beloved relatives or friends and declaring the most dangerous heresies. These visitants will appeal to our tenderest sympathies and will work miracles to sustain their pretensions. We must be prepared to withstand them with the Bible truth that the dead know not anything and that they who thus appear are the spirits of devils.22The Great Controversy, 559, 560. Mar 167.4
Satanic agencies in human form will take part in this last great conflict to oppose the building up of the kingdom of God. And heavenly angels in human guise will be on the field of action. The two opposing parties will continue to exist till the closing up of the last great chapter in this world's history.23The Review and Herald, August 5, 1909. Mar 167.5
