"He who guards his mouth and his tongue, Guards his soul from troubles." Proverbs 21:23

Let's look once again at this issue of controlling the tongue and how it can be possible.
2 Peter 1:3-4 says,
"As His divine power has given to us all things that pertain to life and godliness, through the knowledge of Him who called us by glory and virtue, by which have been given to us exceedingly great and precious promises, that through these you may be partakes of the divine nature having escaped the corruption that is in the world through lust."

It is,
"...By His doing you are in Christ Jesus, who became to us wisdom from God, and righteousness and sanctification, and redemption." 1 Corinthians 1:30 And, "...If any one is in Christ, he is a new creation; old things have passed away; behold, all things have become new." 2 Corinthians 5:17

We have died to the old sin nature. We are now sharers of the divine nature in Christ Jesus.

The Lord has given:
"...beauty for ashes, the oil of joy for mourning, the garment of praise for the spirit of heaviness;"
Why?
"that they might be called trees of righteousness, the planting of the Lord, that He might be glorified." Isaiah 61:3

Jesus said,
"Even so, every good tree bears good fruit; but the bad bears bad fruit. A good tree cannot produce bad fruit, nor can a bad tree produce good fruit.
So then you will know them by their fruit." Matthew 7:17-18; 20

Every good tree by its very nature cannot bear bad fruit and every bad tree by its nature cannot bear good fruit. We see by this that as partakers of the divine nature we do not have to yield to the evil ways of the tongue. As Believers we must keep a diligent watch over our tongue and when the temptations come, and they do, we yield to the indwelling Holy Spirit who leads and guides us.

It would be wise to heed some verses from Proverbs concerning our words such as: (And there are many more.) "When there are many words, transgression is unavoidable, But he who restrains is lips is wise." 10:19 (James 1:19 says,  "...Let every man be swift to hear, slow to speak...")

"Anxiety in the heart of a man weights it down, But a good word makes it glad." 12:25 ("Be anxious for nothing..." Philippians 4:6)

A gentle answer turns away wrath,
But a harsh word stirs up anger." 15:1
("And be kind to one another, tender hearted..."  Ephesians 4:32)

"The tongue of the wise makes knowledge acceptable, But the mouth of fools sprouts folly." 15:2
("A word fitly spoken is like apples of gold..."   Proverbs 25:11)

"A perverse man spreads strife,
And a slanderer separates intimate friends." 16:28 ("A wrathful man stirs up strife..."  Proverbs 15:18)

I will close with the Apostle Paul's admonition to all Believers, "Therefore, I shall always be ready to remind you of these things, even though you already know them, and have been established in the truth which is present with you." 2 Peter 1:12

Lord we praise and honor You. It is from You that all blessings come. We love and adore You Most Holy God! Amen
