Typical Hebrew poetic parallelism – both parts of the verse speak positive things about good people. “The righteous” at the beginning of the verse produce “fruit” which becomes “a tree of life” (see also 3:18; 13:12; 15:4) for him and others. To be able to create something meaningful and share it with others sounds like a nice way to live.
Many of us grew up in churches where there was lots of talk about “soul winning” – folks going out and sharing their faith with others. But when Solomon wrote “he who wins souls” in the second half of this verse, he was not thinking about sharing the gospel with others.
The one who “wins souls” is parallel to “the righteous” at the beginning of the verse. This is a guy whose words, ways and force of personality can move others to join his point of view. The ability to impact people like this makes them “wise” people.
May we always be willing to share our story and how God has made a difference in our lives. May we also be wise in doing so – for the greatest eternal impact in the lives of others!
