"Dr. Wolff traveled in the most barbarous countries without the protection of any European authority, enduring many hardships and surrounded with countless perils. He was bastinadoed and starved, sold as a slave, and three times condemned to death. He was beset by robbers, and sometimes nearly perished from thirst. Once he was stripped of all that he possessed and left to travel hundreds of miles on foot through the mountains, the snow beating in his face and his naked feet benumbed by contact with the frozen ground. GC 361.1"
"In journeyings often, in perils of waters, in perils of robbers, in perils by mine own countrymen, in perils by the heathen, in perils in the city, in perils in the wilderness, in perils in the sea, in perils among false brethren;"
Both passages list various hardships and dangers faced by those who travel to spread their message. The EGW passage provides specific examples from Wolff's life that echo the general list of perils in 2 Corinthians 11:26.
"When warned against going unarmed among savage and hostile tribes, he declared himself “provided with arms”—“prayer, zeal for Christ, and confidence in His help.” “I am also,” he said, “provided with the love of God and my neighbor in my heart, and the Bible is in my hand.”—W.H.D. Adams, In Perils Oft, page 192. The Bible in Hebrew and English he carried with him wherever he went. Of one of his later journeys he says: “I ... kept the Bible open in my hand. I felt my power was in the Book, and that its might would sustain me.”— Ibid., page 201. GC 361.2"
"And take the helmet of salvation, and the sword of the Spirit, which is the word of God:"
Both passages emphasize the importance of spiritual armor and the Word of God as a source of strength and protection. Wolff's statement about being armed with prayer, zeal, and the Bible directly parallels the imagery of Ephesians 6:17, where the sword of the Spirit is the Word of God.
"Thus he persevered in his labors until the message of the judgment had been carried to a large part of the habitable globe. Among Jews, Turks, Parsees, Hindus, and many other nationalities and races he distributed the word of God in these various tongues and everywhere heralded the approaching reign of the Messiah. GC 361.3"
"And this gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come."
The EGW passage describes the spreading of the gospel to various nations, directly echoing the theme of Matthew 24:14, which prophesies the worldwide preaching of the gospel before the end.
