Testimonies for the Church, Volume 9 - Ellen G. White

The Lord must be given an opportunity to show
men their duty and to work upon their minds. No
one is to bind himself to serve for a term of years
under the direction of one group of men or in one
specified branch of the Master's work; for the Lord
Himself will call men, as of old He called the
humble fishermen, and will Himself give them
instruction regarding their field of labor and the
methods they should follow. He will call men from
the plow and from other occupations to give the
last note of warning to perishing souls. There are
many ways in which to work for the Master, and
the Great Teacher will open the understanding of
these workers, enabling them to see wondrous
things in His word.
