In view of the previous mention of humility, which is in many ways foundational, I ought to note that Temperance, as a Cardinal Virtue, includes humility, which is technically, if one digs deeply enough, an accurate and proper love of self (which includes a realization of one’s proper relationship to God).
Now you are really going deep.
I am not a Pastor nor a Bible scholar.
I used to enjoy analyzing the Bible.
I liked looking for patterns and evidence.
Then, I realized that I was studying Christ and not trying to be like Christ.
I had to have the courage to step out in faith.
So, though educated and experienced, I had to start again from the beginning.
It is my experience that courage is the foundation for all the other virtues.
You obviously are experienced and educated.
If you try to grow humility or temperance in a cowardly person, I believe that you will be unsuccessful.
Encourage courage.
Moral courage. Spiritual courage. Intellectual courage.
Then, “As the night follows the day”, the other virtues can grow.
