Jesus clearly viewed children as precious - and that if he loved kids enough to say that adults should be more like them, we should spend more time loving them too.
I'd once heard a spiritual "riddle" that went like this: "What's the only thingin heaven that's the same as it was on earth?"The answer: the wounds in Jesus' hands and feet.
It's fun to talk about heaven, about the throne of God and Jesus and Pop and the daughter we thought we had lost but will meet again someday. But it's not fun to talk about how we got there.
