The Season of Lent is about Jesus.
It isn't about what we give up. It isn't about our fasting. It isn't about hurriedly planning Easter parties. It is about Jesus.
You know how we get those "Jesus is the reason for the season" things floating around in December. It holds true in Lent as well.
Do I encourage you to give something up in Lent, or even fast. Sure. But not as a means of changing you, but as a tool with which to focus upon Christ - as a self discipline that teaches you to turn your eyes off of your belly and onto Christ.
Because Lent is all about watching Christ - it's about watching Him take on Satan and temptation, watching Him take on sin and suffering and death... and then watching Him die, and watching Him rise.
Lent is the season where we watch our Lord, where we take care to remove distractions, where we focus intently upon Him. Don't let it become the season of what you do for Jesus.
