The daily grind of living is only made more fruitful when we take time to use the gifts of the Holy Spirit. While not technically not one of the Seven Gifts of the Holy Spirit, Prudence (a cardinal virtue) is perfected by the Spirit's energy. How often do we move through our day without giving time to self-awareness, reflection on our "I" in action? The lack of a Trinity-diven examination of conscience in one's spiritual life is a pitfall many post-moderns fall into. Any person wanting to know more about him or herself needs to spend time, if only 10 minutes a day, in reviewing points of grace and sin in life up to that point of the day while asking for the grace of root-and-branch conversion. For example, it is has been said that a measure of the person today is how he or she uses free time. Discretion is a fruit of the virtue of prudence; ask yourself if you have been sufficiently discrete in your undertakings.
Spiritual infirmities such as tepidity are caused, not only by chills but also by fevers, that is, by excessive zeal. Saint Paul says, let your service be a reasonable service [Rom. 12:1], because he knew the truth of the words of the Psalmist, the king in his might loves justice [99:4], that is, discretion; and what was prefigured in Leviticus, whatsoever sacrifice you offer, you shall season it with salt [2:13]. In the same vein does Saint Bernard speak: the enemy has no more successful ruse for depriving the heart of real charity than to get him to act rashly and not in keeping with spiritual reasonableness. "Nothing in excess," said the philosopher. And this principle should be our guide even in a matter pertaining to justice itself, as we read in Ecclesiastes, be not over just [7:16]. If one fails to observe this moderation, he will find that good is turned into evil and virtue into vice. He will also learn that many inconveniences follow which are quite contrary to the purpose of the one who so acts.
