One reason for giving authority to Ellen White’s writings that some might have expected me to mention early on was the physical phenomena that accompanied her visions. That she did not breathe, her eyes remained open, and that she was totally unconscious of her surroundings while in vision are all in accordance with the physical phenomena experienced by Biblical prophets. The fact that this is so adds to the authority I give her writings, but I know that Satan can counterfeit physical phenomena. So for me, as with our pioneers, the physical phenomena surrounding Ellen White’s experience lend support for believing in the divine origin of her visions, but are not of themselves coercive proof.

However, if God went to the supernatural lengths that He did to help me know He was speaking through Ellen White, then I better sit up and take notice. After all, in Bible times God considered rejection of His prophets as rejection of Himself. LSS 8.7
