What's that smell? I smell bullshit here. Anyway, the last night's memorial talk was the lamest one I've ever heard. 10% Jesus, 90% Jehovah; not that I'm a christian or something but isn't it supposed to be about Jesus?
I googled "england train accident sacrafice". There are several stories like the one you mentioned, I mean they are stories with the same moral, any of them could be used as an illustration for Jesus' sacrifice.
