How Words limit people and nations:

Luke 1:37 (ASV)
37 For no word from God shall be void of power.
Ecclesiastes 8:4
4 Where the word of a king is, there is power…
Your words are things. And as such, they have the ability to influence the state, condition of your mind and circumstance. What you say is the result of your understanding. And your understanding is a function of your thought. You will speak the right words to yourself, situations, and to other people if only your understanding is right. And you could only understand right if your thoughts are true, pure, just, honest, and lovely (1 Corinthians 13:11 Philippians 4: . The circumstances notwithstanding, the right thought always invariably precedes the right word.
Our beginning texts emphasized a great deal that no word from God is void of power. And since we are spirit beings created in the image and after the likeness of God, a Spirit, our words, also, cannot be void of power.
It stands to reason that, words upon an individual could change the individual’s state of mind and condition; and ultimately change the individual’s life. Words are that powerful.
For the most part, in everyday’s conversation, people use words without understanding the depth and meaning of what they say.
If someone should ask you, have you caught a cold? And you reply, “I’m yet to catch a cold.” Your words suggest that you expect to catch a cold. And you will catch a cold: because expectation is the mother of manifestation.
A man was reported to have never caught a cold. According to this report every time the weather is cold and he noticed symptoms of cold in his body, he simply walks into his bathroom, look straight in the mirror and repeat, severally, the phrase: “I do not have a cold.” And no sooner had he had this done than every symptom of cold would dissipate.
A young man who had limited experience in sales was hired by company X to be a salesman. They weren’t sure whether he would be successful, but they decided to give him a chance. Within six months, he became one of the top salesmen in the company. The board of the company sat him down and enquired of him the secrets of his success, considering the fact that he had little or no experience in the industry.
The young man said, “Every morning when I got into my car, I repeat to myself, I’m the best! I’m the best! I’m the best.’
“I then say, I’m the best salesman in this company. I’m the best salesman in this industry. I’m the best salesman in the business.’
“Before every sales call, I sit in my car and pump myself up by repeating these words, I’m the best in this company. I’m the best in this industry. I’m the best in this country.”’
For many years the Igbo people of South-Eastern Nigeria have been victims of their own words because of an ideology they held onto. The nation Nigeria has three major ethnic nationalities which formed the crust of the political sphere of the country: they are the Hausa’s, the Igbo’s, and the Yoruba’s. The Hausa’s and Yoruba’s have produced successive leaders who have occupied the highest political office in Nigeria, but the Igbo people have never produced any, not since after the Civil War.
Like I pointed out earlier, the Igbo’s are hemmed in by an ideology which they held onto tenaciously. This ideology is the root of their not able to produce a leader for the country. And that Ideology is wrapped in six words, which they affirm vehemently and constantly at any given opportunity. That ideology is: “The Igbo’s do not have a king.”
Say what you want, I believe this claim holds true for the Igbo people of South-Eastern Nigeria.
Whether we know it or not, our words rule us. They could make or mar us. Jesus said they could. In Mark 11:23 Jesus said: “For verily I say unto you, That whosoever shall say unto this mountain, Be thou removed, and be thou cast into the sea; and shall not doubt in his heart, but shall believe that those things which he saith shall come to pass; he shall have whatsoever he saith.”
Notice the clause, “He [you] shall have whatsoever he [you] saith.” What you say are words and you shall have the words you say whether positive or negative.
Put somewhat differently, what we say are expressed thoughts. And our thoughts are what we expect; and what we expect nearly always manifest itself in the third dimension–the physical, material realm because words are spirit and the spirit is of the fourth dimension: the fourth dimension always influences and dominates the third dimension. For example Job experienced in reality that which his mouth, through his thoughts, affirmed: “For the thing which I greatly feared is come upon me, and that which I was afraid of is come unto me” (Job 3:25).
