“Set a guard, O Lord, over my mouth; keep watch over the door of my lips! Do not let my heart incline to any evil, to busy myself with wicked deeds in company with men who work iniquity, and let me not eat of their delicacies!” – Psalm 141:3-4

Why do public speakers use a teleprompter? Of all the possibilities, one important reason is to protect from saying the wrong thing. No matter how sure the speaker may be of their knowledge and ability to say what they should, they are bound to "misspeak". They have learned the danger of being overconfident.

David prayed with great humility and full knowledge of his own heart. He needed the Lord to "set a guard over his mouth" so he wouldn't "misspeak". David was well aware that his heart was "deceitful above all things, and desperately sick" (Jeremiah 17:9) and he needed the Lord's help to stay on track. He had learned the danger of being overconfident.

Have you ever said it wrong my friend? Were you ever led down the wrong path by so called friends? Was your heart deceived or just confused? The Lord is ready to Guard your mouth and direct your steps if you will only call on Him. Be careful to remember the danger of being overconfident.
