i found this as i was doing my daily reading in incandescence: 365 readings with women mystics. It's the reading for November 12 (the one year anniversary of mom's diagnosis).
"As for heaven, I guess you've noticed, God put no doors there.
No, God didn't. and don't you wonder why?
It's because whoever wants to enter heaven, does.
That's how God's love works.
All-merciful, standing there with his arms wide open,
God's waiting--this very moment--
to embrace us and take us into his splendid beauty and kindnesses."
--Catherine of Genoa
(being just a little bit Calvinist, i would maybe even say that God isn't bothering with waiting--God has embraced us already. and being even a little bit more Calvinist i might even say that we aren't capable ourselves of wanting to enter heaven, so God does that for us too. But the point here is the idea, which i love. heaven is doorless (and maybe ugly-pearly-gates-less too!))
