We send it forth, therefore, with the earnest prayer that, while
the book itself may have a limited circulation, yet, through the
providence of God, it may arouse some one to attempt that which seems
beyond our powers and opportunity,--some one who will feel the call of
God; who has the training and the ability; some one who has the spirit
of devotion and self-denial; some one of keen moral perceptions and
lofty faith in the ultimate triumph of justice, who will lead a
crusade that will never halt until Oriental slavery is banished from
our land, and it can no more be said, "The name of God is blasphemed
among the heathen because of you."
