Real sacrifice (Matthew 22; Mark 12)

One of the most touching stories in the New Testament is when the poor widow gives two coins as her offering to the Lord.  Jesus, watching the event unfold, comments to His disciples that this woman gave more than anyone else.  How can that be when she gave so little?  What she gave was a true sacrifice because it actually cost her something.  Everyone else was giving out of their abundance and didn't feel the sacrifice of giving.  I have come to believe that God wants us to give sacrificially in such a way that our lifestyles are affected and that it does cost us something.  If we think about everything we have being a gift from God anyway, it doesn't seem too unreasonable to give back to Him and His purposes.  If God were to assess your financial situation today, would He say that you are a good steward?  Would He describe you as a generous giver?  The poor widow was generous even though she had very little.
