"The Lord has shown me that the message of the third angel must go, and be proclaimed to the scattered children of the Lord, but it must not be hung on time. I saw that some were getting a false excitement, arising from preaching time; but the third angel's message is stronger than time can be. I saw that this message can stand on its own foundation and needs not time to strengthen it; and that it will go in mighty power, and do its work, and will be cut short in righteousness. EW 75.1"
"For he will finish the work, and cut it short in righteousness: because a short work will the Lord make upon the earth."
EGW directly alludes to Romans 9:28 ('cut short in righteousness') in the context of the third angel's message. She uses the phrase to describe the swift and decisive nature of the message's completion.
"And the third angel followed them, saying with a loud voice, If any man worship the beast and his image, and receive his mark in his forehead, or in his hand, The same shall drink of the wine of the wrath of God, which is poured out without mixture into the cup of his indignation; and he shall be tormented with fire and brimstone in the presence of the holy angels, and in the presence of the Lamb: And the smoke of their torment ascendeth up for ever and ever: and they have no rest day nor night, who worship the beast and his image, and whosoever receiveth the mark of his name."
EGW's statement about the third angel's message not being 'hung on time' directly relates to the core message of Revelation 14:9-11, which is a warning against worshipping the beast. While not a direct quote, it emphasizes the importance of the message itself, rather than specific dates.
Then I was pointed to some who are in the great error of believing that it is their duty to go to Old Jerusalem, [See Appendix .] and think they have a work to do there before the Lord comes. Such a view is calculated to take the mind and interest from the present work of the Lord, under the message of the third angel; for those who think that they are yet to go to Jerusalem will have their minds there, and their means will be withheld from the cause of present truth to get themselves and others there. I saw that such a mission would accomplish no real good, that it would take a long while to make a very few of the Jews believe even in the first advent of Christ, much more to believe in His second advent. I saw that Satan had greatly deceived some in this thing and that souls all around them in this land could be helped by them and led to keep the commandments of God, but they were leaving them to perish. I also saw that Old Jerusalem never would be built up; and that Satan was doing h…
"When they therefore were come together, they asked of him, saying, Lord, wilt thou at this time restore again the kingdom to Israel? And he said unto them, It is not for you to know the times or the seasons, which the Father hath put in his own power."
EGW's statement about the error of focusing on Old Jerusalem and neglecting the present work of the third angel's message thematically parallels the disciples' question in Acts 1:6 about restoring the kingdom to Israel. Both passages address the issue of misplaced focus on future events at the expense of present responsibilities.
