"The fruit of the righteous is a tree of life; and he that winneth souls is wise." Proverbs 11:30

RIGHTEOUS, a. ri'chus.

1. Just; accordant to the divine law. Applied to persons, it denotes one who is holy in heart, and observant of the divine commands in practice; as a righteous man. Applied to things, it denotes consonant to the divine will or to justice; as a righteous act. It is used chiefly in theology, and applied to God, to his testimonies and to his saints.

The righteous, in Scripture, denote the servants of God, the saints.

2. Just; equitable; merited.

The first reference to the Tree of Life is in the Garden of Eden. After Adam had eaten of the Tree of Knowledge of Good and Evil, in Genesis 3:22 "And the LORD God said, Behold, the man is become as one of us, to know good and evil: and now, lest he put forth his hand, and take also of the tree of life, and eat, and live for ever:"  The tree is located in the Garden.

We see another reference to the location of the Tree of Life in Revelation 2:7 "He that hath an ear, let him hear what the Spirit saith unto the churches; To him that overcometh will I give to eat of the tree of life, which is in the midst of the paradise of God."

And, in Revelation 22:2, we see that this tree bears fruit - 12 kinds - monthly, and it's a healing fruit, "In the midst of the street of it, and on either side of the river, was there the tree of life, which bare twelve manner of fruits, and yielded her fruit every month: and the leaves of the tree were for the healing of the nations."

The second half of the verse refers to winning souls, "and he that winneth souls is wise." - self explanatory.

So from the text verse, we see that we "Saints", or Servants of God, are to bear fruit and winning souls is in our best interest! 

Winning souls isn't something that should be left to the missionary. When we leave the front doors (or whatever door) of our church, we are entering the Mission Field - OUR mission field. We all have the responsibility to witness to others. And, that doesn't mean we are to be a "silent witness". There are plenty of "good" people out there who are dying and going to hell because WE are not speaking up and telling them about Jesus and what He did for us.
