"the home fields, but in the regions beyond. Thus strength will come to the working forces in other places, and the work of the Lord will advance in His own appointed way. AA 357.3"
"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."
The EGW passage speaks of the work of the Lord advancing in other places, which echoes the sentiment of Acts 1:8 about being witnesses in Jerusalem, Judea, Samaria, and the uttermost parts of the earth. It's a thematic parallel about spreading the gospel.
