Resolve conflict quickly. When discussing an issue, learn to listen more and talk less. You can not resolve conflict if you're talking over one another, no one gets heard. If you can't reach an agreement on an issue and the conversation begins to escalate, just keep quiet and walk away, there can never be an argument if there is only one person talking. However you must respect each other's opininon and allow the other person to get their point across.
Always try to keep peace in your home so that your spirit is not bogged down with confusion and discord.
Matthew 5:9 “Blessed are the peacemakers, for they shall be called sons of God.
