Being "steamed up" creates a blurred vision through the window. It is similar for human behavior. If we are angry and "steamed up" about something, it can blur our vision as we look at a particular situation. Do we lash out at people? Do we harbor grudges against others?
If you are steamed up about something today, be sure it is justified anger. If it is not justifiable, let it go. Do not let your objectivity and your Christian journey be blurred by sin. Walk humbly with your God.
