Are we pregnant with God or is God pregnant with us?

It is always interesting to interpret, especially philosophical and religious French as I did this morning for Rabbi Marc Raphael Guedj who was once more sharing his insights at the Bossey inter-faith summer school. Guedj always insists on the way values inform one another: not justice or charity but charity and justice, not just the letter but also the spirit, not just the spirit but also the letter - he often quotes Emmanuel Levinas' idea that "the letter is the folded wing of the spirit". Not just the written tradition but also the oral tradition. Not just one single and fundamentalist interpretation, but many in discussion and even in disagreement with one another.
Today he took us into rather different territory as he tried to get across the idea of immanence and transendence. At several points he said things along the lines of God being pregnant with humanity, wanting to offer some trace, some outline of Godlikeness to humanity. He spoke movingly of the feminine qualities of God, in the same terms as of the Western (wailing) wall of the Temple in Jerusalem - a totally dependable support. Interesting to think of a feminine quality in those terms. He went on to say that humanity, made in the image of God, is also in some way pregnant with a trace of God, wanting to give birth to that search for the Divine.
The word for pregnant in French in "enceinte" - it has the same root as the French for belt, ceinture, also "une enceinte" is a girded place, within the castle walls for instance. If you want to say in French that a man, or a male gendered object like "un pont", is pregnant it is almost impossible to do this grammatcally - you should say "le pont était enceint" but today of course Rabbi Guedj said "c'est comme si Dieu était enceinte de l'humanité". I really wish I had been able to take notes and so offer more than these fragments of remembered words which went into my ears and sort of came out of my mouth, I do know that I smiled as I heard him say that - knowing that the word "pregnant" in English would not entirely get across the shock of what he had just said.
Thinking about it now it reminded me of Ursula Le Guin's wonderful line "the King was pregnant" in the Left Hand of Darkness. And so I googled and got to this re-reading of Le Guin and now I know one of the books I shall be taking on holiday with me.
So I wonder, what trace of God might I be able to be pregnant with, to give birth to?
