R.A. Torrey emphasizes the significance and effectiveness of personal work in evangelism, illustrating how simple, one-on-one interactions can lead to profound spiritual transformations, as seen in the examples of Andrew bringing Peter to Christ and Edward Kimball leading D.L. Moody to salvation. He argues that personal work is accessible to all believers, can be done anywhere and at any time, and reaches individuals that public preaching often cannot. Torrey asserts that when every Christian engages in personal work, the potential for revival and the evangelization of the world increases dramatically. He encourages the church to recognize this responsibility and privilege, highlighting that personal work, though often overlooked, yields substantial results for the Kingdom of God.
