May the blessings of Jesus be upon you on this solemn feast day.
Regardless of where you are in life, always, always strive for holiness. The Communion of Saints is full of men and women who were the most awful sinners before they repented and changed their lives. It's never too late, and the best time to be holy is now.
I'd also like to extend a gentle reminder that today is a Holy Day of Obligation in the United States.
