In death's case, if you believe in Heaven and they do, you know they'll be happy and safe, but at the same time you'll miss them and wish you had more time with them.
But by the same token, if you believe in an afterlife that lasts FOREVER, the intervening time is hardly going to matter in comparison. I think the reaction - grief - is entirely natural and betrays the fact that if people really sat and thought about it - they wouldn't really believe in what they profess to.
I mean, to be completely honest, next time someone close to you dies, ask yourself if you really believe you will see them again. It's not a nice thought at all, and most people are uncomfortable with the idea of death. But we all have to deal with it and I think we like to ignore it as much as possible.
That other species of animal are seen to undergo grief processes as well belies the origin of the behaviour.
