This is clear instruction from the testimony of Jesus. Is your church a training school? Your church can purchase this manual for its active members, and they can learn to be gospel workers at home, or you can lead a small group through it and train your brothers and sisters to be successful soul winners!
“The formation of small companies as a basis of Christian effort has been presented to me by One who cannot err.” -- CS p. 72.
Start a small group (a company) and go through this manual with them! It can’ t fail!
