There are times when talking is futile: When a person has preconceived ideas. When a person has already made up their minds. When another is always right. When a conversation has changed to an argument. When logic and reason is impossible. When anger rules the emotions. When others don't like you. Each of these are times when it is best to shut one's mouth.
If a discussion is necessary, another time would be best. If a point is true, it will withstand the assaults of others. If a person's mind is made up, there's little chance of changing it and it's best to leave everything in the hands of God.
"But I, like a deaf man, hear not; and I am like a dumb man who opens not his mouth. Yes, I have become like a man who hears not, in whose mouth are not arguments or replies. For in You, O Lord, do I hope; You will answer, O Lord my God." Psalm 38:13-15.
It's possible that even I can't hear for the debates in my own mind. It's possible that the people with whom I want to communicate can't hear me for the same reason. It's times we are at a complete loss for words. In these times, I must step back. Be still. Pray and wait for God's direction. And many times it is He who will answer. Not I. selahv
