3 Set a guard, O LORD, over my mouth; Keep watch over the door of my lips. 4 Do not incline my heart to any evil thing, to practice wicked works with men who work iniquity; And do not let me eat of their delicacies. (Psalm 141:3–4, NKJV)
The enticements of evil are prevalent and powerful. Those who practice sin allure the innocent to join them with offerings of personal pleasure and satisfaction. “Their delicacies” are designed to tempt, but leave the soul famished and starved of righteousness. One’s heart must not be willing to accept the temptations to join with evil and practice sin. Like David, petition God to set a guard over your mouth, that you will not utter compliance and agreement with evil. We cannot eat appetizers from the table of sin, without becoming workers of iniquity. Pray tell: how many delicacies off the table of iniquity can one eat (how much sin can one commit) without causing spiritual harm? To ask such a question is to answer it! Therefore, we must always “depart from evil and do good” (Psalm 34:14; 1 Peter 3:10-11). Do not play around with sin. Protect yourself from the delicacies of those who practice sin. You cannot “partake of the Lord’s table and of the table of demons” (1 Corinthians 10:21).
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 restrain of wisdom and truth. David knew the former would produce no good, and 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 faith (Psa. 39:3-8). His momentary silence gave him the opportunity 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.
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.”
3 But the Lord is faithful, who will establish you and guard you from the evil one. 4 And we have confidence in the Lord concerning you, both that you do and will do the things we command you. 5 Now may the Lord direct your hearts into the love of God and into the patience of Christ. (2 Thessalonians 3:3-5)
Christians are secure in heart and able to endure present trials and live for heaven because the Lord is faithful. Here the apostle explains that the Lord strengthens and protects His disciples from evil as they “do and will do the things we command you” (v. 4). There is no expectation of divine resolution to strengthen and protect the Christian who is given to disobedience (the “disorderly” of verse 6). Let us not fight against the apostolic commands. By continually obeying them the Lord will direct you into God’s love and the steadfast endurance which gives eternal comfort. The Lord is faithful. The probing question is, are we?
