That's just one Christmas. Most Christmases get special attention - practical and spiritual. Easter too. There were special preparations leading up to our wedding day and also for the days our sons were born - practical preparations so that these days would go well but spiritual preparations too, hoping that what we said and did on these occasions would maybe whisper the gospel into someone's listening, searching ear.
But what about the day of our death? A bit hard to prepare for in lots of ways. Death may come suddenly and unexpectedly. Or it may come at the end of a long, slow illness or at the end of the gradual process of aging, leaving us too debilitated and tired by the time we get there to do much about it.
But what is death? For the Christian it is the day we fall safely into the arms of Jesus. That last breath drawn marks the beginning of glorious, eternal life with our Father in heaven.

It isn't easy reading in lots of ways. The various writers don't make light of the physical reality and pain of death which makes this book very confronting. Nor do they make light of the sadness and tragedy of death. Jesus himself wept when his friend Lazarus died - weeping not just for the loss of his friend but also over death itself, that His Father's perfect creation had become so stained and sullied by sin as to be marred by the ugliness of death.
For the one who dies loving Jesus, death has lost its sting. Because when the last breath of life is drawn, the Christian passes away from this life into eternal life with Jesus. And while this book has plenty to say about the pain of death, it has more to say about the wondrous glory of what lies beyond it.
But back to the issue of preparing for the day of one's death - because this book is not just about dying well. It's about living well because therein lies the preparation for death. It is best summarised by the second last paragraph of the book, penned by Richard Sibbes:
Therefore, if we desire to end our days in joy and comfort, let us now lay the foundation of a comfortable death. To die well is not a thing of that light moment as some imagine: it is no easy matter. But to die well is a matter of every day. Let us daily do some good that may help us at the time of our death. Every day by repentance pull out the sting of some sin, that so when death comes, we may have nothing to do but to die.
(From "God Reserves the Best for the Last" by Richard Sibbes (page 158) in O Love That Will Not Let Me Go edited by Nancy Guthrie.)
As I said, this book is confronting in many ways. But it is also rich with comfort, encouragement and hope. As for all the books in this series, it is definitely worth reading. And reading it would be time well spent.
