Where is Jesus?

At dinner tonite, out of the blue, Joshua asked us, "Where is Jesus?" I was busy watching Cal football, so I left Annette to the tough answers. As Annette explained heaven and how Jesus could be with us if we asked him to "come into our hearts", Joshua replied, "I don't want him to come in." OK. No pressure. This faith thing is very abstract for an almost 3 yr old (and for the rest of us as well.)
