Those who guard their lips preserve their lives,
but those who speak rashly will come to ruin.
Proverbs 13.3
The tongue is a fire,...
sets the whole course of one's life on fire...
James 3.6
May the words of my mouth and meditation of my heart
be pleasing in Your sight, O Lord, my Rock and my Redeemer.
Psalm 19.14
The Psalm implies that the words of our mouth come from our heart. Jesus confirms this in Mark 7:20-23--"it is from within, out of a person's heart, that evil thoughts come...malice, lewdness, slander..."
Proverbs 6. 16-19 tells us there are seven things that "God hates" and are "detestable to Him." Three of these have to do with the tongue--lies twice, and "a person who stirs up conflict in the community." A fourth is "a heart that deises wicked schemes."
The Proverbs have several dozen comments of the tongue, lips, words and mouth.
The Psalms are all about the heart that is the source of all we say, as well as do.
James 3.1-4.8 gives us guidelines for "taming the tongue."
3.1-8 tells us the power of the tongue, concluding, "No human being can tame the tongue. It is a restless evil, full of deadly poison."
3.9-12 gives us some examples of how important this is.
At 3.13 James gives us insight into how the tongue works and how God purifies our words by dealing with our heart.
Our prayer for our words and heart is Psalm 19.14 (Psalm 139.23-24 and all of Psalm 119 will help). As we search Psalms and Proverbs for Scriptures, we will find "swords of the Spirit" (Heb. 4.12; Eph. 6.17) "attack" the bitter envy and selfish ambition, the fights and quarrels, the desires that battle within us, the coveting and wrong motives of selfish pleasures that James identifies for us.
Proverbs and Psalms, again, are key sources for "the word of God" that we need to resist "earthly, unspiritual, demonic" (James 3.15) words that come from "dark...spiritual forces of evil." (Eph. 6.12)
This work will free us from our internal conflicts that show up in our conflicts with others.
