"Fifth European Missionary Council Again, in 1887, Mrs. White spent the month of June in Scandinavia. In company with Mrs. Ings she had attended very interesting meetings with the little companies of Sabbath keepers in Voh-winkel and Gladbach, Germany. In these meetings Elder L. R. Conradi had acted as guide, interpreter, and fellow laborer. LS 300"
"For we are labourers together with God: ye are God’s husbandry, ye are God’s building."
The EGW passage mentions Elder Conradi acting as a 'fellow laborer,' which directly echoes the sentiment in 1 Corinthians 3:9 about being 'laborers together with God.' While not a direct quote, the shared concept and language make this a valid thematic parallel.
"At Copenhagen there was seen an encouraging growth in the church since the last visit. A busy week was spent there. LS 300.2"
"And so were the churches established in the faith, and increased in number daily."
Both passages describe the growth and establishment of churches. The EGW passage speaks of encouraging growth, while the Bible verse speaks of churches being established and increasing in number.

Ten tents had been pitched in a beautiful grove, and in these about one hundred were accommodated, while fifty more found lodgings in near-by houses. The delegates from America and Central Europe were cared for in a large, comfortable house overlooking the Christiania Fiord. LS 300.4"
"But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judea, and in Samaria, and unto the uttermost part of the earth."
Both passages describe the spreading of the gospel to different regions. The EGW passage lists various locations and people involved in missionary work, while the Bible verse speaks of being witnesses in Jerusalem, Judea, Samaria, and to the uttermost part of the earth.
