Wow! That definitely was a different take on the traditional theology. It reminds of the famous Bob Dylan line, "Did Judas Iscariot have God on his side?"

Anyway, I guess the best suggestion, I could make for improving it, would be to flesh it out a little bit. Try to get into the minds of the characters of God and Lucifer, to tell us how they truly feel about this arrangement. Of course, Lucifer isn't happy, but does God have any regrets. As of now, they're both kind of flat.

On a less profound note, this story contains a few technical errors, not the least of which is that the title misspells "sacrifice". Another problem is this sentence, "He loved God for than anything," should be "he loved God more than anything." and "these angels are looking for leader to rebel" needs an article.

Actually, all in all, I get the feeling that this was written rather quickly. With some all around revision, it could be much better.
