Proverbs 18:7
7 A fool’s mouth is his destruction, and his lips are the snare of his soul.
I have met people that at first seemed like they hold so much knowledge. They seem intelligent, but as they keep talking you start noticing that they lack details that are paramount to the exact thing they speak of. That is when you begin to see they lack the true knowledge that they claim to hold. You see if you let fools talk, they will eventually show you how little they know. The thing is, I have also begin to see Christians with this same problem. They have heard someone else speak of the Bible and that is what they go off of. The problem is that by doing this you may not fully receive the true meaning of the scripture you speak. You may miss an important word that is needed. You have to read the scripture to become wise in it. You have to study and let it fully imbrace your thoughts. If you do not, you risk being made a fool. Do not be the fool who talks without knowledge.
