In the multitude of words sin is not lacking, but he who restrains his lips is wise (Proverbs 10:19, NKJV).
Unrestrained words lead to foolishness, sin, and sorrow. The wisdom of restraining our tongues is reiterated by James, “So then, my beloved brethren, let every man be swift to hear, slow to speak, slow to wrath; for the wrath of man does not produce the righteousness of God” (James 1:19-20). Consider some of the sins that arise when one is captured by “the multitude of words.” (1) The sin of pride in one’s eloquence. Although we are confident the apostle Paul had command of rhetoric and eloquence, he made it a point not to parade such abilities when preaching the gospel (1 Cor. 2:1-5). Likewise, while eloquent, Apollos drew attention to the Scriptures and not himself (Acts 18:24-25). His humility prepared him to learn the way of God more accurately (Acts 18:26). Pride enters in when we try to impress others with many words. (2) The sin of misguided prayers. Jesus said, “And when you pray, do not use vain repetitions as the heathen do. For they think that they will be heard for their many words” (Matt. 6:7). God’s attention is not gained by many words but by a contrite heart (Luke 18:13-14). God is not impressed by the multitude of words. After all, He made man’s mouth (Exod. 4:11). (3) The sin of foolishness. Wisdom advances righteousness and avoids evil by knowing when to speak and when to be silent (Eccl. 3:7). Fools spread slanderous insinuations, rushing headlong to their destruction, but “wisdom is found on the lips of him who has understanding” (Prov. 10:18, 14, 13).
1 I said, “I will guard my ways, lest I sin with my tongue; I will restrain my mouth with a muzzle, while the wicked are before me.” 2 I was mute with silence, I held my peace even from good; And my sorrow was stirred up. 3 My heart was hot within me; While I was musing, the fire burned. Then I spoke with my tongue:” (Psalm 39:1–3, NKJV)
David took special care when wicked people were before him. He knew the ungodly, if given a chance, would unjustly turn their evil against him. They did so frequently throughout his life, without justification. When confronted by evil people, David chose to carefully guard his conduct and his words, lest he should fall into sin himself, and become “the reproach of the foolish” (Psa. 39:8). We may feel the impulse to lash out against the wicked, instead of speaking with the restraint of wisdom and truth. David knew the former would produce no good. Plus, it would fail to express the hope he had in the Lord and His deliverance from evil (Psa. 39:7-8). Like David, we should be “slow to speak” and “slow to wrath” when the wicked are before us. Even as he sighed with sorrow and grief of heart over the wickedness before him, David did not speak until he could do so as an expression of his faith and hope in the Lord (Psa. 39:3-8). His momentary silence allowed him to guard his ways, gather his thoughts to avoid sin, and then to speak fearlessly with faith in the Lord. It is a mark of spiritual maturity to remain calm, composed, and faithful when evil is before us (Jas. 1:19-20).
Whoever guards his mouth and tongue keeps his soul from troubles. (Proverbs 21:23, NKJV)
Our words are the expressions of our soul. The deepest recesses of the heart are exposed by the words of our mouth. Truly, “out of the abundance of the heart the mouth speaks” (Matt. 12:34). For example, guard your mouth against speaking corrupt words. There is no place in the Christian’s life for profanity, for it exposes a profane heart. Guard your mouth against speaking lies. Half-truths, misdirection and other forms of deception are not a trait of the pure in heart. “Let each one of you speak truth with his neighbor” defines the followers of Jesus (Eph. 4:25). Guard your mouth against angry words. These flow out of a heart that is bitter, resentful and unforgiving. Guard your mouth against speaking false doctrine. The Spirit of truth has spoken truth to us through Christ’s apostles (Jno. 16:13). Therefore, speak “as the oracles of God,” not with the wisdom and will of men (1 Pet. 4:11; Col. 2:8). By cleansing your heart of profanity, deceit, anger and error, your soul will be protected from trouble. That’s what repentance is; changing your heart. Rather than opening wide your mouth to pour out evil things, guard your soul from the troublesome results of an uncontrolled tongue. May we recall and live what the children sing, “Be careful little mouths what you say.”
