Pr 10:31
³¹ The mouth of the righteous flows with wisdom,
But the perverted tongue will be cut out.

 The Parts:

flows – “bears fruit,” “brings increase”

perverted – root means to “turn, over turn.” Often used of sin connected with the mouth, Pr2.12; heart, Pr6.14; eyes, Pr16.30; mind, Pr23.33.

cut off – also cut out, cut down. Beyond its literal meaning, it pictures: root out, eliminate, remove, excommunicate, destroy.

Sharpening for my life today:

This gem of wisdom opens for us the fruit of speech. Wisdom, skill in living, involves a right attitude and approach to all areas of life, speech being one of the very important ones! At the core of this wisdom is edification, that is, building up others, which is fundamentally what loving someone is about.

A distinct way of not loving is “words turned upside down.” Here we would find all facets of untruth, deception, “white lies” (where did such foolish thinking ever come from? It takes the blood of the Savior to cleans “white lies”! There is no such thing!), denials, etc. It is very much worth noting that this motivation to harm others is met with God’s harm of the one who so practices this perversion! This truth of life is called talionic justice, or, by the measure which you measure it will be measured to you, or, what you sow you reap!

Take some time and think about “fruit bearing words.” This isn’t the “form” of the words, it’s the “results” of the words. Are your words bearing fruit, building up, bringing a blessing?

Consider the New Testaments’ direction, Eph4.29-31 . . . 
²⁹ Let no unwholesome word proceed from your mouth, but only such a word as is good for edification according to the need of the moment, so that it will give grace to those who hear. ³⁰ Do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption. ³¹ Let all bitterness and wrath and anger and clamor and slander be put away from you, along with all malice.

Col4:6
⁶ Let your speech always be with grace, as though seasoned with salt, so that you will know how you should respond to each person.
