“May the LORD cut off all flattering lips, the tongue that makes great boasts, those who say, “With our tongue we will prevail, our lips are with us; who is master over us?”
Psalms 39:1 I said, “I will guard my ways, that I may not sin with my tongue; I will guard my mouth with a muzzle, so long as the wicked are in my presence.”
Psalms 119:9 How can a young man keep his way pure? By guarding it according to your word.
1 Kings 2:4 that the LORD may establish his word that he spoke concerning me, saying, ‘If your sons pay close attention to their way, to walk before me in faithfulness with all their heart and with all their soul, you shall not lack a man on the throne of Israel.’
2 Kings 10:31 But Jehu was not careful to walk in the law of the LORD, the God of Israel, with all his heart. He did not turn from the sins of Jeroboam, which he made Israel to sin.
Proverbs 4:26 Ponder the path of your feet; then all your ways will be sure. Do not swerve to the right or to the left; turn your foot away from evil.
Hebrews 2:1 Therefore we must pay much closer attention to what we have heard, lest we drift away from it.
Proverbs 21:23 Whoever keeps his mouth and his tongue keeps himself out of trouble.
Psalms 73:8 They scoff and speak with malice; loftily they threaten oppression. They set their mouths against the heavens, and their tongue struts through the earth.
Psalms 141:3 Set a guard, O LORD, over my mouth; keep watch over the door of my lips!
James 1:26 If anyone thinks he is religious and does not bridle his tongue but deceives his heart, this person’s religion is worthless.
James 3:2 For we all stumble in many ways. And if anyone does not stumble in what he says, he is a perfect man, able also to bridle his whole body. If we put bits into the mouths of horses so that they obey us, we guide their whole bodies as well. Look at the ships also: though they are so large and are driven by strong winds, they are guided by a very small rudder wherever the will of the pilot directs. So also the tongue is a small member, yet it boasts of great things. How great a forest is set ablaze by such a small fire! And the tongue is a fire, a world of unrighteousness. The tongue is set among our members, staining the whole body, setting on fire the entire course of life, and set on fire by hell. For every kind of beast and bird, of reptile and sea creature, can be tamed and has been tamed by mankind, but no human being can tame the tongue. It is a restless evil, full of deadly poison.
I am not sure about you but many of these verses speak to my heart. Read them again and again. May God’s quiet voice speak to our heart and mind keeping us from speaking that which does not honor or glorify Him at all times.
