Answer ...
Soul Winning is simply taking the Gospel of Jesus Christ to the lost. It is usually more than just a tract or a witness.
Soul Winning is taking evangelism from start to finish. From
opening questions to a prayer for salvation, if possible.
Of course,
God is the one who actually wins the soul to Himself. Man's
part in soul winning is the presentation and encouragement for the
lost person to trust fully in Jesus Christ for salvation.
"The fruit of the righteous is a tree of life; and he that winneth souls is
wise." Proverbs 11:30
