Proverbs 12:25 (NKJV)
If you want to start a fire, you need the necessary elements, fuel, and oxygen; with these things, you can easily start a fire. But, if you start a fire and add water, the fire will go out. If you take away either fuel, or oxygen, you will also be without a fire. This same thing is true in many other situations. To have a certain thing, you need to have the elements necessary to properly create that thing, but even if you have the right elements, and you add something else, you will change what you had at first.
One thing that some people struggle with more than others is anxiety, which can lead to depression. The dictionary says that anxiety deals with a concern about some trouble, some problem that may come at some time. Everyone can have a feeling of anxiety when they hear some negative news, but it is what we do with that feeling that matters. When someone is dealing with anxiety, or depression, that is a problem, but the Bible tells us that a good word can make the heart of someone with depression glad.
If someone is dealing with anxiety and stress in their heart, in their life, Proverbs 12:25 says that a good word will make them glad, and a good word would certainly include God's Word. On the other hand, if someone is hearing a "bad word", that can lead to anxiety and depression. If we focus on and talk about the negative side of life, it will bring anxiety, stress, and depression. But by focusing on and saying the right things, by saying what God says in His Word, we can successfully deal with anxiety, stress, and depression in our own life and in someone else's life.
