God is not God of the dead but of the living; in his sight all are alive.
(Revised English Bible; OPB)
That second clause in an addition in Luke (cf. Mark 12:27, Matthew 22:32). I think it’s an important addition. If God exists outside spacetime then all humans are equally alive, and bounded.

Thank you, Lorna. I like it in Mark and Matthew too, but I found it difficult to get my head round. The extra clause makes it a bit easier to approach I think.
