In Victor Hugo's "Les Miserables," the notion of love is central to human happiness. The quote suggests that for those who truly love, their joy already exists in the affection they share, and divine intervention is meant only to extend this happiness indefinitely. It highlights the idea that true fulfillment comes from deep emotional connections rather than material or external factors.

Furthermore, the statement implies that love alone is sufficient for a meaningful life, with eternity being the only addition that God can grant. This perspective emphasizes the timeless nature of love, suggesting that what matters most is the quality of our relationships and the way they enrich our existence, rather than the fleeting pleasures of life.
