"Christ has given His commission: “Go ye into all the world.” Mark 16:15 . All must hear the message of warning. A prize of richest value is held up before those who are running the Christian race. Those who run with patience will receive a crown of life that fadeth not away. 9T 136.1"
"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.
