I do not believe in God -- any god. I strive to be a good atheist and person by setting an example of decency to all and service to my community. The whole "good without god" thing.
In raising my 6 and 7 year old sons, I've always responded to the rare god/heaven/religion questions with as "That's what some people believe, but lots of people including me don't." That's been easy in the abstract, and I pride myself on not lying to or indoctrinating them with bogus beliefs I don't share.
But my mom is dying...soon. She's been given "weeks to months" to live. I've got my own grieving to do, but But better and lesser people than me have gotten through it, and so will I. She's religious and counting on the afterlife, I believe I'm saying goodbye for ever.
Facing this very real situation I find myself debating the advantages/drawbacks of letting them believe the myth that grandma's looking down on them from heaven to help them cope/grieve. I sure won't be the one telling them that, but they're gonna hear it from left and right, and when they ask me about it I think I'm going to bite my tongue and say "yup." I'm thinking of it like Santa Claus and the stockings -- a short term lie/myth that I ignore/perpetuate until they're old enough to consider the facts/faith and decide for themselves.
Net-net, I want to help my kids cope with the loss of their grandmother,
don't want to foster indoctrination, don't want to be a dick, etc.
