"Be careful to maintain the elevated character of the missionary work. Let all connected with our missions, both men and women, be constantly inquiring, “What am I? and what ought I to be and to do?” Let all remember that they cannot give to others what they themselves do not possess; therefore they should not settle down content with their natural ways and habits, seeking to make no change for the better. Paul says, “I press toward the mark.” [ Philippians 3:14 .] There must be constant reformation, unceasing advancement, if we would perfect a symmetrical character. GW 462.3"
"I press toward the mark for the prize of the high calling of God in Christ Jesus."
Ellen White directly references Philippians 3:14 in this passage.
