Lamentations 3:37 (NKJV)
Our words are very important; what we say about ourselves and our life will have an impact on us. This principle is something that we see in the Bible but the truth of this principle has been misunderstood and neglected by many people. Often even when something is true but it is used in the wrong way people have a negative attitude towards that thing. Our words, our confession, is one of these things. While it is true that our words are important and our confession will have an impact on our life, many people struggle with this because they fail to understand the underlying principle of confession.
Some people have had the idea that if they just repeat something for a long enough period of time that it will produce results. But it is not the amount of times or the length of time we say something that really matters. That would be like what Jesus said about how the Pharisees thought that their prayers would be heard because they used "many words" (Matthew 6:7). Just saying something we want to have happen one thousand times is not the most important thing, the most important thing is if what we say is in agreement with what God has already said.
We need to be sure that the things we say about every area of our life is what God has said in His Word about every area of our life; God will always stand behind His Word. God's Word will not return void but it will accomplish what it was sent to do (Isaiah 55:11) and God will watch over His Word to bring it to pass (Jeremiah 1:12). There is power in the words we speak when we speak God's Word. When our words are in agreement with God's Word that is when we will see the greatest results in our life.
