"In the future life the mysteries that here have annoyed and disappointed us will be made plain. We shall see that our seemingly unanswered prayers and disappointed hopes have been among our greatest blessings."
"And we know that all things work together for good to them that love God, to them who are the called according to his purpose."
Ellen White teaches the same doctrine — that apparent disappointments are actually blessings — which is the experiential application of Paul's promise in Romans 8:28.
"The burden of labor for these needy ones in the rough places of the earth Christ lays upon those who can feel for the ignorant and for such as are out of the way. He will be present to help those whose hearts are susceptible to pity, though their hands may be rough and unskilled. He will work through those who can see mercy in misery, and gain in loss. When the Light of the world passes by, privilege will be discerned in hardship, order in confusion, success in apparent failure. Calamities will be seen as disguised blessings; woes, as mercies. Laborers from the common people, sharing the sorrows of their fellow men as their Master shared the sorrows of the whole human race, will by faith see Him working with them. Ed 270.2"
"Come unto me, all ye that labour and are heavy laden, and I will give you rest. Take my yoke upon you, and learn of me; for I am meek and lowly in heart: and ye shall find rest unto your souls. For my yoke is easy, and my burden is light."
The passage speaks of Christ laying a burden of labor on those who feel for the ignorant, which parallels Jesus' invitation to take His yoke and learn from Him.
"“The great day of the Lord is near, it is near, and hasteth greatly.” Zephaniah 1:14 . And a world is to be warned. Ed 270.3"
"The great day of the Lord is near, it is near, and hasteth greatly, even the voice of the day of the Lord: the mighty man shall cry there bitterly."
Ellen White directly references Zephaniah 1:14 in this passage.
"And I saw another angel fly in the midst of heaven, having the everlasting gospel to preach unto them that dwell on the earth, and to every nation, and kindred, and tongue, and people, Saying with a loud voice, Fear God, and give glory to him; for the hour of his judgment is come: and worship him that made heaven, and earth, and the sea, and the fountains of waters."
The call to warn the world of the approaching judgment is a central theme in Revelation and aligns with the urgency expressed in this passage.
