"When Christ looked down from the crest of Olivet, He saw this state of things existing in every church. The warnings come down to all that are following in the tread of the people of Jerusalem, who had such great light. This people is before us as a warning. By rejecting God's warnings in this our day, men are repeating the sin of Jerusalem. The Lord sees what the human agent does not see and will not see—the outcome of all the human devising in Battle Creek. He has done all that a God could do. He has flashed light before the eyes of the people, that their sins might not reach the boundary where repentance cannot be felt. But by a long process of departure from just and righteous principles, men have placed themselves where light and truth, justice and mercy, are not discerned. This course has become part of their very nature. 8T 68.1"
"And when he was come near, he beheld the city, and wept over it,"
Both passages involve looking upon a city (Jerusalem/Battle Creek) and lamenting its spiritual state and impending doom due to rejecting God's warnings. The EGW passage explicitly draws a parallel between the people of Jerusalem and those in Battle Creek.
"I call upon all who have united in a course of action that is wrong in principle, to make a decided reformation and forever after walk humbly with God.... 8T 68.2"
"He hath shewed thee, O man, what is good; and what doth the Lord require of thee, but to do justly, and to love mercy, and to walk humbly with thy God?"
The phrase "walk humbly with God" is a direct quote from Micah 6:8, making this an explicit allusion.
"These are no idle tales, but truth. Again I ask: On which side are you standing? “If the Lord be God, follow Him: but if Baal, then follow him.” 1 Kings 18:21 . 8T 68.3"
"And Elijah came unto all the people, and said, How long halt ye between two opinions? if the Lord be God, follow him: but if Baal, then follow him. And the people answered him not a word."
The EGW passage directly quotes 1 Kings 18:21, making it a clear and explicit allusion.
