Most of the bible stories are pagan--including resurrection of Lazarus--a most important event (and probably the last miracle) that could not be recalled by the first three gospel writers!!!
There are clear parallels between the "Jesus raising Lazarus" story and the Egyptian "Horus raising "El-Azar-Us" or "El-Osiris" story.

Internal proof is the most pronounced one. Lazarus who received such a great reward from Jesus never came forward to speak in support of Jesus during the mockery of his trial, nor came for preaching word after Jesus's death.
If youths of today can volunteer for IS and similar terrorist organization which they know would only bring eventual destruction, why did Lazarus not come forward for Jesus?
