Chapter 8 describes parental love as a kind of giving that never feels complete. Parents give time, money, energy, and affection, yet still feel they have not given enough. Real love does not keep a ledger.
That makes parental love one of the most accessible human windows into God’s love. It is not transactional, and it does not wait for return before continuing to give.
The chapter treats this as part of what makes parental love holy. Love becomes most like God when it stops counting and starts pouring itself out gladly.
