We atheists are a sorry lot. Something good (or tragic) happens to someone and what have we got to say?
Wishing you all the best!
I’m so sorry.
But aren’t the real gems theistic?
Go with god. (Via con dios if you’re feeling international)
Godspeed. (My favourite, though I’m not sure what it actually means)
Bless your heart.
I’m certain there must be more that I can’t think of at the moment. Please add at will and then share if, as an atheist, you feel comfortable invoking god as a heartfelt gesture or expression.
From your lips to god’s ears…
