Sacrifice is not just something of the movies; it is an every day occurrence. In 9th grade I choose to do a history day project on sacrifice in the Boxer Rebellion. Specifically, I did a group performance on a missionary family, Charles, Eva Jane, and Florence Price. I read a book full of letters written mostly by Eva to her family and friends. This missionary family gave up life in the United States to go share the gospel with the "heathens" of China. The family worked to build belief in the salvation of Christ throughout Fen Chow Fu for many years. They mainly wanted to equip Chinese Christians to hold their own church services and Bible studies. After four or five years the Boxer uprising began, though it did not immediately affect the Prices. It did spread to areas near the family, but the Prices stayed longer to help others in peril. Once they did choose to leave, they were murdered on their way out of the country. The Price family gave the ultimate sacrifice for what they held most dear, they gave their lives. Missionaries around the world make sacrifices and I believe that qualifies them for cool sacrifice.
There is sacrifice all through movies as well. One movie that comes to mind is Pan's Labyrinth. The little girl in the story makes a large sacrifice in the end to help someone else (I won't say exactly what it is in case you haven't see it). She does gain something out of her sacrifice, but it is still a sacrifice. Rick gains something out of his own sacrifice, which makes me wonder what exactly qualifies as a sacrifice in life. It seems you can still gain something from your sacrifice, but not gain too much. Where is the line drawn?
