Michael: "So, on Good Friday Jesus died to save our souls, and on Sunday he was born again to un-save them?"
He had asked what was the difference between Christmas, Easter and your birthday. Birthday was easy, and with the others I did my usual blurrily vague job of conveying the Christian essentials. At no stage did I mention souls. I think he hears accurate and cogent Christian information at after-school care, and like everything else, it sticks.
