"There are lots of able-bodied men who, if they could only have a little more faith in God, and could realize the calamities that are coming upon the earth, and the responsibilities of that priesthood that God has conferred upon them, they would be ready to break all barriers and say, Here I am, send me; I wish to benefit the human family."

- John Taylor, Teachings of Presidents of the Church: John Taylor, (2011), 66–76, Chapter 8: Our Missionary Duty
