Isaiah 55:11 - So shall my word be that goeth forth out of my mouth: it shall not return unto me void, but it shall accomplish that which I please, and it shall prosper in the thing whereto I sent it. (KJV)

The word of God waters your life just as rain waters the earth. The word is like the rain as it goes into the earth and causes it to bud to bring forth fruit. The words that come out of God's mouth will accomplish what He has sent it to do. If you accept it, and you believe it and you let it abide there, it will bring forth fruit. Why? It is the power. It will not return void. Notice once again the word is sent to do something, but while it is doing it, it is accomplishing something.
When you put the word on a problem you have, it begins immediately working on that problem. You might say how can that be? Thanks for asking. It works for us just as it works of God Himself. In Genesis chapter 1 we see God creating the earth. Notice that everywhere it says "and God said" not too far past it you see "it was so". In other words, when God speaks something, it always comes to pass.

Isaiah said that word will not return void. It will accomplish what it was sent to do. Look at how God created the world. He created it with His words by speaking it into existence. He said the words, and it happened. He said "light be". Light was. He said "Man be." Man was. When He speaks it comes to pass. Why? Because His word is always backed up with the power. His word is the power.

A good example of this is in the workplace. Most of us, if not all of us, have a boss somewhere. We work on a job. When the boss comes in and says, "I want you to do this." You say, "And what if I don't?" The boss looks back at you and says, "You don't, and you don't come back tomorrow." You believe that. Why? The boss has the power to back that up. He said, "You aren't coming back tomorrow. Clean out your desk and go home." So you are going to do what he says, because he has power.

In the same way, when God says something it is so. Why is that? When He speaks there is the power to bring it to pass. The power is right there in His word. It is the power unto salvation; it is the power unto healing; it is the power of God for whatever you need. That is the nature of the word of God.

You can take His word and put it in your mouth. Water your life with the word of God. Create your world with your words, words from the word of God. When you speak the word of God it shall be just as you say. Why? The word is power. The words you speak will be backed by heaven to cause whatever you say to come to pass in your life. Healing may be what you want. If so, then say what the word says about your healing.

Hold fast to it, and it shall come to pass.
