What are the motifs in Lament for a Son by Nicholas Wolterstorff?

Faith in Christianity is a recurring idea in this book. There are many references and allusions to the Christian Bible; several of these are Job 7: 9-10, Job 14:1, Isaiah 40, Isaiah 45:15, Psalms 18:36, Psalms 42, Psalms 116: 15, and Psalm 126:2. A reference to Revelations mentions that during God's reign on Earth, there will be no more death or mourning for the old order of things will pass away.
