Sympathies to all bereaved by the loss of Kenneth Lewis. Incidentally I have a friend with the same name! However, do think seeing him again is possible? Sure! John 5 : 28 - 9. Everything that Kenneth Lewis did, said, felt, experienced, loved, despised, feared e.t.c God recorded. So bringing him back is possible with God. He will do so in a coming Paradise.
