"With the beginning of this work of publishing, we did not cease our labors in preaching the truth, but traveled from place to place, proclaiming the doctrines which had brought so great light and joy to us, encouraging the believers, correcting errors, and setting things in order in the church. In order to carry forward the publishing enterprise, and at the same time continue our labors in different parts of the field, the paper was from time to time moved to different places. LS 127.1"
"Therefore they that were scattered abroad went every where preaching the word."
Both passages describe believers traveling and preaching the word. The EGW passage describes the Whites' travels alongside their publishing work, while Acts 8:4 describes believers scattered abroad preaching. The core theme of spreading the gospel through travel is present.
"Let all things be done decently and in order."
The EGW passage mentions 'setting things in order in the church,' which aligns with the principle of orderliness advocated in 1 Corinthians 14:40. While not a direct quote, the principle is clearly reflected in the EGW passage.
