No emotionality is wonderful. God gave us our emotions. But they need an owner: the human will and the intellect (well formed, morally so), otherwise the emotions have a tendency to “bark” and lead people around and confuse them and make them sad, or at least leads them to living a spurty life, sometimes happy, but quickly sad.
Doesn’t this ring true with people you know? Up and done, prone to moods.
We should never serve our emotions.
We instead serve God, by knowing the truth (the job of the intellect) and doing the good (the job of the human will).
A person who has learned this ordering is one of the most “stably happy” person you will ever meet, since they are not slaves to their emotions, they are truly free, free to serve God, free to do good. They are always smiling, always working, always talking to God. They attract others, they spend their time serving others because they have a deep and lively friendship with God. God’s spirit is spilling out in them. But the rarely examine their emotions unless they’re training them again. They don’t live this way so that they can feel good…they seek to serve God.
A moody person is a slave to their emotions. Their emotions are unmortified. Their emotions bark or wag and the person follows their commands. The “dogs of emotions” own the owner. Always trouble ahead in this case.
