Words are primarily meant for creation not communication. Communication occurs through words but we must not lose sight of the primary use of words.
In the chapter 1 of the book of Genesis, God illustrated the creative power of Words. He spoke the world into existence. God created us in His own image therefore His intent is that we be co-creators.
It's time that we learn the power of words. Avoid the careless use of words. You must learn to create by your words. Death and life are in the power of the tongue; choose. Deut 30:19. Pro 18:21.
