How do we know that Jesus really came back from the dead?

Several lines of evidence can be sighted. First, an entire religion, (Christianity) has resulted from the belief that Jesus was crucified and subsequently resurrected from the dead. Second, if we apply the same historical tests of accuracy to the biblical New Testament documents (which state that He did), that we apply to other texts of similar periods, the evidence is compelling. Third, 11 out of 12 of the original Apostles were killed because they were unwilling to deny that Christ rose from the dead. It is totally implausible that these men would have died for a lie. Other evidence is strong as well, including non-biblical writings whihc support the biblical texts.
