Consider that the more damaged or diseased our brains become, the less we can think, remember or perceive. What then happens when our brains are completely dead? Do we quit thinking altogether? What are the implications for the afterlife? Do we receive new more perfect brains of a sort? How will that affect our personality and sense of identity? Will we truly be “ourselves”. I suppose that is something to ponder with the imperfect brains we currently possess.
We fear God by honoring, reverencing, and cherishing Him. His greatness and majesty reduce us to an overpowering sense of awe that is not focused only on His wrath and judgment but also on His transcendent glory , which is like nothing else we can confront in this world. It leaves us all but speechless.
