Death is a process with the body providing signs that it is approaching.
To live in a manner worthy of our human dignity, and to spend our final days on this earth in peace and comfort, surrounded by loved ones—that is the hope of each of us. In particular, Christian hope sees these final days as a time to prepare for our eternal destiny. Today, however, many people fear the dying process. They are afraid of being kept alive past life’s natural limits by burdensome medical technology. They fear experiencing intolerable pain and suffering, losing control over bodily functions, or lingering with severe dementia. They worry about being abandoned or becoming a burden on others.
