"Dangers in Speculative Study The light of truth which God designs shall come to the people of the world at this time is not that which the world's men of learning are seeking to impart, for these men in their research often arrive at erroneous conclusions and in their study of many authors become enthused with theories that are of satanic origin. Satan, clothed in the garb of an angel of light, presents for the study of the human mind subjects which seem very interesting and which are full of scientific mystery. In the investigation of these subjects, men are led to accept erroneous conclusions and to unite with seducing spirits in the work of propounding new theories which lead away from the truth. 9T 67"
"And no marvel; for Satan himself is transformed into an angel of light."
The EGW passage explicitly refers to Satan appearing as an angel of light, which is a direct allusion to 2 Corinthians 11:14.
"A messenger from heaven stood in our midst, and he spoke words of warning and instruction. He made us clearly understand that the gospel of the kingdom is the message for which the world is perishing and that this message, as contained in our publications already in print and those yet to be issued, should be circulated among the people who are nigh and afar off. 9T 67.2"
"And this gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come."
The EGW passage directly echoes the sentiment of Matthew 24:14, emphasizing the importance of spreading the gospel message to the world. The connection is strong and intentional.
