Chapter 4 argues that life is not first. Love is first, because life itself is born within love and exists to move more deeply into it. Human beings are born from love, raised by love, tested by love, and meant to return to eternal love.
That reframes the purpose of existence away from mere survival, achievement, or autonomy. A life can be outwardly successful and still miss its deepest meaning if it does not become more capable of love.
This is why the chapter can connect birth, marriage, parenthood, and death into one arc. They are not separate episodes but stages in a single education of the heart.
