Hebrews 4:12 

For the word of God is alive and active .sharper than any double-edged sword, it penetrates even to dividing soul and spirit, joints and marrow ; it judges the thoughts and attitudes of the heart.

The words you write or speak to others can leave a huge impact and create a lasting memory--either good or bad--so it's super important to choose them wisely. The thing about real life is, when you do something stupid, it normally costs you. In books the heroes can make as many mistakes as they like. It doesn't matter what they do, because everything works out in the end. They'll beat the bad guys and put things right and everything ends up cool. In real life, vacuum cleaners kill spiders. If you cross a busy road without looking, you get whacked by a car. If you fall from a tree, you break some bones. Real life's nasty. It's cruel. It doesn't care about heroes and happy endings and the way things should be. In real life, bad things happen. We all make choices, but in the end our choices make us.When you choose an action, you choose the consequences of that action. When you desire a consequence you had damned well better take the action that would create it. Be wise today so you don't cry tomorrow. The human tongue is a beast that few can master. It strains constantly to break out of its cage, and if it is not tamed, it will run wild and cause you grief.The tongue has no bones, but is strong enough to break a heart. So be careful with your words. Don't mix bad words with your bad mood. You'll have many opportunities to change a mood, but you'll never get the opportunity to replace the words you spoke. One kind word can change someone's entire day. Words have energy and power with the ability to help, to heal, to hinder, to hurt, to harm, to humiliate, and to humble. Words are seeds that do more than blow around. They land in our hearts and not the ground. Be careful what you plant and careful what you say. You might have to eat what you planted one day. I end this post with this final thought. If we understood the power of our thoughts, we would guard them more closely. If we understood the awesome power of our words, we would prefer silence to almost anything negative. In our thoughts and words, we create our own weaknesses and our own strengths. Our limitations and joys begin in our hearts. We can always replace negative with positive.
