Hello ,
Tim Keller tells the following story about the power of Christ's resurrection:
A minister was in Italy, and there he saw the grave of a man who had died centuries before who was an unbeliever and completely against Christianity, but a little afraid of it too.
So the man had a huge stone slab put over his grave so he would not have to be raised from the dead in case there is a resurrection from the dead. He had insignias put all over the slab saying, "I do not want to be raised from the dead. I don't believe in it."
Evidently, when he was buried, an acorn must have fallen into the grave. So a hundred years later the acorn had grown up through the grave and split that slab. It was now a tall towering oak tree.
The minister looked at it and asked, "If an acorn, which has power of biological life in it, can split a slab of that magnitude, what can the acorn of God's resurrection power do in a person's life?"
