I was playing with my five-year-old grandson. My daughter had told me that he was starting to ask theological questions. So I asked him one. ‘Who is God?’
He grinned at me and said, ‘Turn around!’
I turned to look behind me – nobody was there.
Again he said ‘Turn around!’
Again, no one was there.
‘So, tell me, who is God?’ I asked him again.
‘Missus/Mister Nobody!’ he answered with a mischievous smile.  [Choose which title works for your audience.]

…nor can /God/ be expressed or conceived, since /God/ is neither number nor order, nor greatness nor smallness; nor equality nor inequality, nor similarity nor dissimilarity….

Dionysius, The Mystical Theology

To reach satisfaction in all, desire its possession in nothing. To come to possession in all, desire the possession of nothing. To arrive at being all, desire to be nothing. To come to the knowledge of all, desire the knowledge of nothing.

To meet God, one must let go of all assumptions and attachments along the way. One must seek nothing and nobody, no-body.
