"territory. Thus they began to depart from God. By their failure to carry out His purpose, they made it impossible for Him to fulfill to them His promise of blessing. Is not the church of today doing the same thing? With the whole world before them in need of the gospel, professed Christians congregate where they themselves can enjoy gospel privileges. They do not feel the necessity of occupying new territory, carrying the message of salvation into regions beyond. They refuse to fulfill Christ's commission, “Go ye into all the world, and preach the gospel to every creature.” Mark 16:15 . Are they less guilty than was the Jewish church? COL 303.2"
"And he said unto them, Go ye into all the world, and preach the gospel to every creature."
Ellen White directly references Mark 16:15 in this passage.
