George Campbell Morgan was a noted preacher in London till he died in 1945. He tells of a time when travelling in Italy,
'I saw the grave of a man who had died centuries before who was an unbeliever and vehemently against Christianity, but a little afraid of it too. So the man had a huge stone slab put over the grave so he would not have to be raised from the dead in case there is a resurrection form the dead. He had insignias put all over the slab saying, 'I do not want to be raised form 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. I looked at it and wondered, if an acorn, which has 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?'
The resurrection of Christ is not just an historical event (challenged I know by many but ably backed by the evidence) but brings with it a power to change our time and our eternity. Take a listen here (be patient, he starts speaking after a couple of minutes!!) to a mind stretching talk on the resurrection by Tom Wright the current Bishop of Durham.
