If by sacrificing your life you could contribute so much to the world that you would be honored in all nations, would you be willing to do so? If so, would you make the same sacrifice knowing that someone you thoroughly disliked would receive the honor while you went unrecognized?
The idea behind a sacrifice is that something valuable is being given up for the greater good. The credit for it shouldn't matter. If someone is willing to make a sacrifice, then they shouldn't be thinking about what they'll get out of it, even if it's posthumously. If they're doing it for the credit, they're doing it for the wrong reasons. Pretty sure Jesus wasn't thinking about how the Church would be worshiping him for the next 2000 years while he was hanging on the cross. He did what He did out of love for the world, not for the recognition. So yeah, if a small sacrifice on my part (and anything on my part would be incredibly small compared to Christ's sacrifice) would bring about any contribution to the world for the better, I'd be willing to do it, whether I got the credit or not.
