Anytime the word spoken by man passes through the atmosphere, it produces pattern, which always last for years. The early scientist said that, every word spoken by man is registered in the atmosphere for six thousand years, while the bible says, “Men will give account of every spoken word remains till the day of judgment”.
Every word spoken by man remains in the atmosphere for as long as lifetime and it is easily readable by the spirit, both good and bad. When you proclaim an evil word against yourself, your Children, or somebody else the word is registered in the atmosphere serving as a command for the evil spirit to use in tormenting the person concern.
While proclaim good words on yourself and others serves as command for every good spirit to work on.
So care must be taken in the use of our tongue, not for cursing, abusing but for blessing.
