Which is no sign at all, they cant even see it.
Hi Rokurac,
This is incorrect. Those during the time of Jesus were EYE witnesses as to the fact that like Jonah being in the belly of the whale, so too Jesus would be in the belly of the earth and rise on the third day. They saw the stone rolled away and Jesus wasn't there; he had risen. They SAW this with their eyes.
We who are generations later believe by faith. The nation of Israel SAW with their eyes that Jesus had risen on the 3rd day.
