"The tongue has the power of life and death" also refers to gossip. Many marriages have fallen because of this.
The tongue has the power of life and death,
and those who love it will eat its fruit.
This verse from Proverbs speaks for itself.
Those that tell others of their sicknesses, just get more sicknesses.
Or they will get the backlash of saying anything negative.
Psalm 101:5; Whoever slanders their neighbor in secret, I will put to
silence; whoever has haughty eyes and a proud heart, I will not tolerate.
Ephesians 4:29; 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.
James 1:26; Those who consider themselves religious and yet do not keep a tight rein on their tongues deceive themselves, and their religion is worthless.
What is here on this page is great and if you apply these Bible verses, there is no reason that your life should not change for the better.
But there is so much more in the new book God, us, and Satan. I really recommend you purchase it. There are many links to Bible verses and my notes accompany most of them. And many pictures.
Seeing that many churches, institutions, and people were giving an incorrect version of the Bible, I set out to correct it, not only for myself but for others. I wanted God known as He is and as I found Him. I wanted people to have the truth, so I spent 8 years studying and unraveling God's messages to us from the original languages.
Many commentaries and pictures.
