"and rebel, ye shall be devoured with the sword.” Isaiah 1:18-20 . The message, “Go forward,” is still to be heard and repeated. The varying circumstances taking place in our world call for labor that will meet these peculiar developments. The Lord has need of men who are spiritually sharp and clear-sighted, men who are certainly receiving manna fresh from heaven. The Holy Spirit works upon the hearts of such men, and God's word flashes light into the mind, revealing to them more than ever before the true wisdom. 6T 149.3"
"Come now, and let us reason together, saith the Lord: though your sins be as scarlet, they shall be as white as snow; though they be red like crimson, they shall be as wool. If ye be willing and obedient, ye shall eat the good of the land: But if ye refuse and rebel, ye shall be devoured with the sword: for the mouth of the Lord hath spoken it."
Ellen White directly references Isaiah 1:18-20 in this passage.
