I am giving up some things. I decided to stop drinking alcohol for the duration. And sweets. I am going to read the New Testament. Maybe do a scripture reading at dinner with the family. And we, as a family, are giving up frivolous spending. By the end of Lent I will have a few extra bucks to donate to charity.
Mostly, Lent is a time of recognizing our failings and offering them to God, who seems to receive them with such grace and love, as though they were the most precious gifts we could give him. I lay them at your feet, my sweet Jesus.
