"I have been repeatedly shown that our presses should now be constantly employed in publishing light and truth. This is a time of spiritual darkness in the churches of the world. Ignorance of divine things has hidden God and the truth from view. The forces of evil are gathering in strength. Satan flatters his co-workers that he will do a work that will captivate the world. While partial inactivity has come upon the church, Satan and his hosts are intensely active. The professed Christian churches are not converting the world; for they are themselves corrupted with selfishness and pride, and need to feel the converting power of God in their midst before they can lead others to a purer or higher standard. 9T 65.2"
"For, behold, the darkness shall cover the earth, and gross darkness the people: but the Lord shall arise upon thee, and his glory shall be seen upon thee."
Both passages discuss spiritual darkness covering the earth. The EGW passage expands on the idea of spiritual darkness and the need for light and truth, which aligns with the theme of Isaiah 60:2.
