Interpret this church sign please

[Gregory]

I pass by a local church everyday. Once a week they post a different saying on their sign like "God answers knee-mail".

This week the sign reads: "God doesn't have any grandchildren".

What does this mean? I am not being snarky when I say I truly don't "get" this and it bothers me. It bothers me that it bothers me.

See here and here. Kidder nailed it.

This week the sign reads: "God doesn't have any grandchildren".

It means that God is dead, and his genes have not been passed on.

It means that God is dead, and his genes have not been passed on.

Did God win a Darwin Award?
