And as Jesus was going up to Jerusalem, he took the twelve disciples aside, and on the way he said to them,  "See, we are going up to Jerusalem. And the Son of Man will be delivered over to the chief priests and scribes, and they will condemn him to death
 and deliver him over to the Gentiles to be mocked and flogged and crucified, and he will be raised on the third day." Matthew 20:17-19 (ESV)
Jesus gives himself willingly. He seems to know with acute clarity what will happen. He knows what waits for him in Jerusalem, as he speaks of himself in the third person as the son of man.
It will be the Son of Man, not a man, but man, who will be tried and crucified, the son, not a son. Here is the divine sacrifice, the ultimate scapegoat, the perfect substitute, The Son of Man, and he goes willingly to his fate. No one catches him off guard. No one snookers him. He knows what waits, and with all the nobility of man he goes forward, he goes on, he sacrifices himself that others may live. That is the most noble a thing a man can do, to sacrifice his life for others. This is why society honors and reveres the military. And this is why for conservatives it is anethema that women should serve. Men are to go to war to protect women and children, women should not have to protect men. It is the last ditch attempt to save a doomed society that women should have to protect men, who are capable of defending themselves. But this is off topic.
Where men can sacrifice their lives so that others live perhaps a bit longer, so that society knows a modicum of peace, and law and order, that perhaps a few who would have otherwise died today can instead die tomorrow, that is all a man can hope to accomplish. It sounds perhaps futile when put that way. But then when one loves his society and desires that his children be afforded the same opportunities as him, and that his loved ones be not molested with violence and the horrors of occupation and servitude, then one sees the nobility of self sacrifice. Freedom of religion, and the values of western society are things I think worth sacrificing for, especially that my son, and perhaps grandchildren of the future, as well as all of society be able to hear the gospel and enjoy the Christian faith that makes it worth it. Finally, it is this sacrifice of Christ, that makes the other self sacrifices worth it, indeed makes even life worth it, whatever it is.
See, Jesus when he sacrifices himself, he does so that others not only live to die tomorrow, but that he might make it possible for them to live forever. He sacrifices himself that all might live, and have eternal life. This is his gospel, that he died for you, and rose on the third day. This is why he is worthy of worship. He made it possible for you to live, and thereby gives meaning to your life. Because that he rose from the dead, means that you to will rise from the dead.
