A lying tongue hateth those that are afflicted by it; and a flattering mouth worketh ruin.
Good words do not prove good intentions. Liars and flatterers are out to destroy you, no matter how good their words sound, no matter their excuses (Pr 26:24-25). A wise man rejects both kinds of men, just as David did (Ps 101:3-8). If you tolerate these deceitful people in your life, they will take you down (Pr 20:19; 29:5). They are hiding hatred and destruction behind their lying words, and noble and prudent men will stay far from them.
A man lies for advantage or to protect himself. He is selfish and wicked, so he feels no guilt about deceiving you in order to advance himself. It does not matter what his relationship is to you or how kindly he speaks at other times. If he has lied to you, then you should run far from him, whether it is a slander about you or a lie to your face. His deceit proves that he hates you. He is out to hurt you or use you. True friends never lie.
Flattery is praise designed to deceive you into doing what the flatterer wants you to do. It is a form of lying, but it is harder to detect and resist. Men love praise, so they are easily lulled to sleep by flattery. It is poison in a spoonful of honey. A flatterer is more dangerous than a slanderer, for he is crafty, friendly, and subtle in working his deceit, while liars are more easily detected by their open malice and wickedness.
Are you vigilant and intolerant against deceivers? Aggressive salesmen may lie or flatter to sell an inferior product. Many girls have lost their virginity or women their marital fidelity to lying flattery of whoremongers (II Sam 13:1-13). Many men have been led to hell by flattering lies of whorish women (Pr 2:16-18; 5:3; 6:24-26; 7:5,21-23). Many citizens have voted for corrupt politicians due to flattery and false promises, for the election process in most nations is based on words rather than character or performance.
Parent, you must punish lying and flattery, and you must teach children to reject liars and flatterers (Job 32:21-22). Teach them that God hates liars, He will judge them, and liars are going to hell (Pr 6:16-19; Job 17:5; Ps 12:2-3; Rev 21:8). Teach them that friends who tell the truth even when it hurts are better than kisses from an enemy (Pr 27:5-6). Teach them that men should be judged by their actions and lives, not words (Pr 20:11).
Religion has many lies and flattery, for the devil has used it since Eden (Gen 3:1-13; John 8:44). The Jews flattered and lied to Jesus to trap him (Luke 20:20-21). False teachers use good words and fair speeches to deceive simple hearers (Rom 16:17-18). Rome tells the lies of abstaining from meat and marriage (I Tim 4:1-3). But God’s faithful pastors and teachers never use flattering speech or lies (II Cor 2:17; 4:2; I Thess 2:3-6).
Jehovah is God of truth, and so is His Son Jesus Christ, Who is Faithful and True (Rev 19:11). He expects honesty and truthfulness from His children, and He punishes all liars and flatterers. All who take His name must make sure their every word is honest, sincere, and true – and obviously so in the ears of all others (Deut 32:4; Rom 12:17; I Pet 2:12).
