Sacrifice

I've been looking for a real sacrifice, something more, something worthy. Maybe my thoughts are in the wrong place. I mean, I know that I can never repay God for his ultimate sacrifice, and never will be able to, but I just think that there is so much more to give... I read that the early disciples of Christ, the beginning Church fasted, not to ask God for something, but because it was cheaper not to eat and they could give more to the people in need, the poor, the hungry, the lost. What am I doing? What is this love that I have that doesnt reach farther than my arms, that never reaches beyond my own meager, selfish desires? Everything is provided, and God is so great and good and powerful, shouldnt that mean that I give freely what is so graciously given to me? Shouldnt there be a TRUE sacrifice? Shouldnt there be something missing that was not given out of an excess, out of too much? Shouldnt I feel something, like they felt that hunger in their somaches? I want that emptiness, not because I have need, but because I sacrificed.
