We imagine that God lives beyond our earthly realm. We cannot see “him” around us or in the heavens, therefore believe this to be true. We can never enjoy his company here and hope to do so after we transfer from this life to another. We are then given a wish to rest in peace.
But peace too is illusory and that wish is passed onto the departing randomly. There is no guarantee. Tear down that wall and realize the within and you shall know God and peace.
