In my theology class, I had an assignment on how the church views the operation of grace and sin in Section Three of the Catechism.
I was very much taken with the description of the virtues. I think the examination of the virtues is a good way to examine oneself.
In looking at myself, I find that I am most deficient in the theological virtue of charity, and most deficient in the cardinal virtue of temperance.
So I am praying for both of these things; that the Holy Spirit fill me with both.
