This book was a beautiful meditation on death and how essential it is to think about during all stages of life. No, not as morbid as it sounds - quite cheerful actually!
Some quotes:
"Dietrich Bonhoeffer once wrote to a friend, 'it is only when one loves life and the earth so much that without them everything seems to be over that one may believe in the resurrection and a new world.' This perspective fits perfectly with what Jesus has promised and nothing we've said about about death awareness changes anything. Jesus draws our attention to the grave to break our attachment to foolish hope in false gods, but not to pull us back from joy. He would rather return the good things of life to their proper place in our minds and hearts: they are gifts, not gods. We can fully enjoy them, knowing we'll lose them, precisely because we know we don't have to have them. We can open our hearts to temporary pleasures precisely because we don't give our hearts to temporary pleasures. We can only love them for what they are, not preoccupied by what they're not, when we love them not for their own sake but for the true fountain of joy from which they flow. They are wonderful conduits to joy in God, to be loved for God's sake for as long as we have them."
This quote from Augustine sums it up well too "To enlighten and enable us, the whole temporal dispensation was set up by divine providence for our salvation. We must make use of this, not with a permanent love and enjoyment of it, but with a transient love and enjoyment of our journey, or of our conveyances, so to speak, or any other expedients whatsoever ..., so that we love the means of transport only because of our destination."
"We sometimes judge the plausibility of God's promises to us in light of what we're experiencing now. We are tempted to believe that if God is allowing us to suffer as we are, we can't trust him to deliver on his promise of redemption, resurrection, and an eternal life of joy with him. We can view his promises as an upgrade to an already-comfortable life, icing on the cake of the pleasant ease that is our baseline expectation. But this is not how his promises come to us in Scripture ... If his promises are no more to us than icing on the cake of good lives now, then those promises will always seem irrelevant and otherworldly when we suffer.
"... this honesty about death then prepares me for what is truly surprising: that God the Son subjected himself to the imitations, brokenness, and death that are normal for us."
