Speech
As we live today ,their is one greatest way that we use to communicate to each other,speech is the widely used form of communication that the world has adopted ,and this has been understood as "language", when we search the Bible from Genesis to revelation all we see from page to page is someone talking about something, Proverbs says we need to be quick to hear and slow to speech,why because what you say is what people widely say defines you as a whole, Jesus Christ carefully processed his words before speecking about anything, therefore before you speecking you need to process everything cause it matters what you say.
