Upon Jesus' death on the cross, the Temple curtain was torn in two, there was an earthquake and dead believers rose up from the ground, coming back to life.
"The captain of the guard and those with him, when they saw
the earthquake and everything else that was happening, were
scared to death. They said, 'This has to be the Son of God!'"
Matthew 27:54 (The Message)
