Let the Testimonies be judged by their fruits. What is the spirit of their teaching? What has been the result of their influence? All who desire to do so can acquaint themselves with the fruits of these visions. For seventeen years God has seen fit to let them survive and strengthen against the opposition of Satan's forces and the influence of human agencies that have aided Satan in his work. CCh 93.1
God is either teaching His church, reproving their wrongs and strengthening their faith, or He is not. This work is of God, or it is not. God does nothing in partnership with Satan. My work ... bears the stamp of God or the stamp of the enemy. There is no halfway work in the matter. The Testimonies are of the Spirit of God, or of the devil. As the Lord has manifested Himself through the Spirit of prophecy, past, present, and future have passed before me. I have been shown faces that I had never seen, and years afterward I knew them when I saw them. I have been aroused from my sleep with a vivid sense of subjects previously presented to my mind; and I have written, at midnight, letters that have gone across the continent and, arriving at a crisis, have saved great disaster to the cause of God. This has been my work for many years. A power has impelled me to reprove and rebuke wrongs that I had not thought of. Is this work from above or from beneath.120Testimonies for the Church 5:671 CCh 93.2
