Answer:
The New Testament writings contend that the resurrection was "the beginning of His exalted life" as Christ and Lord. Jesus is the "firstborn of the dead," prōtotokos, the first to be raised from the dead, and thereby acquiring the "special status of the firstborn as the preeminent son and heir.", The Bible tells us that Jesus died and rose again not only so that we could receive forgiveness, but even more so, He died and rose again so that we might have life. It is through His death and resurrection that we receive life. ... Christ died and rose again that we might live through Him - that's salvation.
a) They sent a runner to Athens to tell them of the victory and he said, "Victory is ours!" and then died of exhaustion is your answer.
The Battle of Marathon was well known, because while Athens was able to beat the much stronger Persian army, it was also where the term "marathon", and the event that "marathon" is used to describe was born.
The runner that they sent ran non-stop (typical of a marathon) from the battle field to Athens to deliver the news of victory. However, after getting there & delivering the news, he died, possibly from exhaustion.
