As a parent, grandparent, and children's minister, I know full-well how powerful and hair-raising it can be to say "you can't have that!" or "we don't have that anymore!" Children are creatures of habit and can be stubbornly focused on "what's mine" and "where's mine." And of course, we adults never quite outgrow that!
It's this basic human nature that makes the practice of "fasting" -- giving something up for Lent such a great teaching opportunity and memory-setter for the season.
Over the last couple of decades, we've seen more and more Protestant churches embracing what had been largely a Catholic practice, namely, "giving something up for Lent." So it's not surprising that in some Protestant churches we've also seen the a swing toward "doing" something for Lent, instead of "doing without."
Some have "given up on giving up" because they think it's too self-centered or too easily interpreted as "doing it to please God." They prefer a spirituality that gives, not gives up, an outward-facing spirituality, not an inward one.
But it's a false dichotomy, and an unbiblical one.
Jesus practiced and encouraged solitary contemplation and fasting. He even gave us instructions! See Matt. 6:16-18. The entire idea of Sabbath which is a fast from work -- was created by God on the 7th Day to remind us to focus on what's most important -- your God and your family. In that sense, "giving up something for Lent" is an "act of Sabbath." We put lesser things, hard to put-away things on a "mini Sabbath."
With regard to "giving up something for Lent," this biblical practice takes place on the heels of Epiphany, a season full of celebration. It balances the excesses of what might be called a "Christmas hangover," and forces us to consider the less-triumphal aspects of Christ's life and message -- beginning with his 40 day fast in the wilderness. Rather than focusing on Christ's message to "do likewise," Lent focuses on Christ's message about the inward conversation with God, and the practices that can help us overcome temptations great and small.
I don't want to overstate the importance of "giving up for Lent." It can be kind of a gimmick, but that's why it needs to be done thoughtfully and with follow up.
"Giving up for Lent" can also be a kind of "entry level spiritual practice" for our kids. It can be a great way to INTRODUCE them to the stories and concepts of Lent and Holy Week. By making it a kind of game of "can you do without this?" we're able to begin the conversation about resisting temptation -- and that's certainly a life skill that we and Jesus would approve of!
