Ellen White does not explicitly state that only those who accustom themselves to hardships and privations will make it through the time of trouble. However, she emphasizes the necessity of developing a strong and enduring faith to withstand the challenges of that period.
Ellen White highlights the importance of a faith that can endure hardship. She writes, "The season of distress and anguish before us will require a faith that can endure weariness, delay, and hunger,—a faith that will not faint, though severely tried" (
GC88 621.2). She also notes that "That season of distress and anguish will require an effort of earnestness and determined faith that can endure delay and hunger, and will not fail under weakness, though severely tried" (
3SG 135.1). This suggests that those who develop such a faith will be better prepared for the difficulties of the time of trouble.
Ellen White uses Jacob's experience as an example of the kind of perseverance needed. She explains, "Jacob's experience during that night of wrestling and anguish represents the trial through which the people of God must pass just before Christ's second coming" (
PP 201.1). She also states, "Jacob prevailed because he was persevering and determined" (
GC88 621.2). This illustrates the importance of unwavering faith and determination in the face of adversity.
