Montie,
I think you are missing the whole idea of giving something up for lent. The idea is to help prepare ourselves for Christ’s death and resurrection by in some small way by forgoing something that we enjoy. To gladly sacrifice even as our saviour sacrificed himself for us. Since when does making an honest mistake lead to sin? Our Lord is not sitting around waiting for us to mess up, he already knows we will…we are human!
The lenten season is about preparing yourself to receive the awesome gift that Jesus gave us by dying for us. I don’t know about you, but I wonder if I can ever prepare enough for that. During lent in my house, I encourage my kids to truly give up something that hurts…for one kid it may be candy, another pop, yet another tv watching. The point I always make to them is when they are tempted, to think about Christ up on the hill without food or water for 40 days with the devil tempting him, and then look at how trivial their sacrifice is knowing that in the end they crucified him. If you mess up, make a point to pray about it and move on, or maybe, sacrifice a little more the next day…like if you gave up fast food and forgot until after you ate at Sonic…maybe you could resolve to fast for a day, or give up meat on Wednesdays and Fridays. It is a disappointment to yourself at your failure but not a sin.
