On the third day the tomb is empty: He is risen.
The story
Very early on the first day of the week the women come to the sepulchre and find the stone rolled away. An angel declares, "He is not here: for he is risen, as he said." Jesus appears to Mary Magdalene, to the disciples and to more than five hundred brethren, and forty days later ascends to heaven.
What it teaches
Because He lives, death is defeated and all who believe in Him shall live also.
