Power of the tongue

Power of the tongue

written by Deinah May 19, 2020

Whether you believe this to be true or not, words have power. “Death and life are in the power of the tongue”. Meaning, our tongue can be used as a weapon of destruction or as a fountain of life. It can restore or destroy relationships, families, reputations, careers, even your own health.


What is expressed verbally can change everything – it all starts in your brain. According to a study done by Andrew Newberg, M.D. and Mark Robert Waldman, words can alter expressions of genes, strengthen areas in our frontal lobe and promote cognitive functioning. One negative word can trigger the activity in the amygdala making it to release stress-producing hormones and neurotransmitters, which interrupts our brain functioning. Once our brain functioning is interrupted, it affects our logic, our reason and our language. Same can be said when using positive and uplifting words — it also affects the brain. It activates the part of your brain called the Reticular Activating System (RAS). This part makes the words we repeat over time, become part of who we are — they become our reality.

Now when we read Joshua 1:8, it all kind of makes sense. “This book of the law shall not depart from your mouth, but you shall meditate on it day and night, so that you may be careful to do according to all that is written in it; for then you will make your way prosperous, and then you will have success”. When we meditate on God’s promises and we speak them out, it becomes our reality changes.

Isn’t it amazing how God’s intricate design of the human body shows how as human beings we are fully equipped and capable to abide to His word?


With all this said, use your words. Use them wholesomely because once said, you can’t take it back. “Do not let any unwholesome talk come out of your mouths, but only what is helpful for building others up according to their needs, that it may benefit those who listen” (Ephesians 4:29).

Insanity is doing the same thing over and over again and expecting a different result. If you want things to be different, you need to change the way you speak.

What is coming out of your mouth today, life or death?
