Proverbs 16  Sprinkled throughout this chapter are nuggets of wisdom about:

Making plans
V 1 "The plans of the heart belong to man, but the answer of the tongue is from the Lord."
V2 " All the ways of a man are clean in his own sight, but the Lord weighs his motives." 
V3 "Commit your works to the Lord and your plans will be established." 
V 9 "The mind of man plans his way, but the Lord directs his steps." 
V25 "There is a way which seems right to a man, but its end is the way of death." 

Our plans, our intentions and purposes, start then, in our hearts and minds.  We think they are right and clean and good. But, there is only one way that this can be so.. if they are committed to the Lord!
For it is our Sovereign Lord who sees our real intentions and knows where our plans might really lead us.  We have to go back to Proverbs 3: 5-6, leaning not on our own understanding, but acknowledging Him in all our plans so that He can establish our paths.  Here is the wisdom that we must live by! Our every plan, intention, and purpose... submitted to and committed to Him, Who knows what is best for us. 

Being leaders -
A king is responsible for "divine" decisions. V10
He must be careful to "not err in judgement" 
It is disgusting to the Lord when a king commits wickedness. v12
A position of authority "is established on righteousness" 
"Righteous lips are the king's delight, and he who speaks right is loved." v 13
"The wrath of a king is as messengers of death, but  a wise man will appease it." v14
"In the light of a king's face is life, and his favor is like a cloud with the spring rain." v15

Think about these words in light of our current political system!  The leader who has the fear of the Lord and commits his way to the Lord, has everything to gain.. for his way will be established. But those who "err in judgement" and commit wickedness will gain only God's wrath.  How we need to pray for our president and senators and congressmen - that they will not err in judgement and commit wickedness, but would speak and do what is right.

And again, more words about our mouths!
Verse 21 " ... and sweetness of speech increases persuasiveness." 
Verse 23 "The heart of the wise teaches his mouth, and adds persuasiveness to his lips."
Verse 24 "Pleasant words are a honeycomb, sweet to the soul and healing to the bones." 
Verse 27 "A worthless man digs up evil, while his words are as a scorching fire." 
Verse28 " A perverse man spreads strife, and a slanderer separates intimate friends." 

James wrote about this too. "And the tongue is a fire, the very world of iniquity, the tongue is set among our members as that which defiles the entire body, and sets on fire the course of our life and is set on fire by hell." (James 3:6) To tame the tongue, he tells us, " If anyone does not stumble is what he says, he is a perfect man, able to bridle the whole body as well." ( v2)  What is the cure for this? There is only one. " But the wisdom from above is first pure, then peaceable, gentle, reasonable, full of mercy and good fruits, unwavering, without hypocrisy . " (v17)
We must:
"submit to God" (4:7);
"Draw near to God" ( 4:8) and
"Humble yourselves in the presence of the Lord.." (4:10)

In Christ, Paul wrote, "are hidden all the treasures of wisdom and knowledge." ( Col. 2:3)  And so I pray:

Father in heaven, may the peace of Christ rule in my heart today. May His words richly dwell in me, with all wisdom and with thankfulness.  May all I do in word or in deed, be done in the name of the Lord Jesus, as I give thanks through Him to You, God, the Father. Amen.  ( Col. 3:15-17)
