"and others were hired for the meeting. When completed, the camp had over one hundred tents, and five hundred and eleven people. The grounds were well laid out and faithfully cared for. Many of the tents were furnished with bedsteads, tables, chairs, and bureaus; and the whole camp was a model of cleanliness and good order. LS 346.1 “We felt that the eye of God was upon all our arrangements,” Mrs. White wrote when referring afterward to these painstaking efforts to make the grounds appear attractive and inviting; “and in the order of our camp we sought to show forth the praises of Him who hath called us out of darkness into His marvelous light.” 1 Peter 2:9 . The results attained were much greater than the toilers had dared expect. “The encampment made the impression upon those who visited it,” Mrs. White wrote further, “that the truth we advocated was of great importance, that the missionary spirit is the true spirit of the gospel. LS 346.2"
"But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people; that ye should shew forth the praises of him who hath called you out of darkness into his marvellous light:"
Ellen White directly references 1 Peter 2:9 in this passage.
"“This was the first camp meeting that Melbourne had seen, and it was a marvel of wonders to the people. Far and near the sound went out concerning this city of tents, and a most wonderful interest was awakened. Every afternoon and evening the tent was filled to its utmost capacity, not with a cheap order of society, but with people of intelligence, physicians of note, ministers, and business men. We saw that with the blessing of God this camp meeting would do more to bring our work before the people than years of labor could possibly do. LS 346.3"
"These were more noble than those in Thessalonica, in that they received the word with all readiness of mind, and searched the scriptures daily, whether those things were so. Therefore many of them believed; also of honourable women which were Greeks, and of men, not a few."
Both passages describe a positive reception of a religious message by an intelligent and influential audience. Acts 17:11-12 highlights the noble Bereans who eagerly received the word, while the EGW passage describes the positive impact of a camp meeting on intelligent and influential people. The connection is thematic and relevant.
