Thérèse had a vivid sense of how human love is not diminished in heaven but intensified, and she looked forward to being able to love her sisters even more in the glorified life of heaven.

I was like an idiot... No one ever cause you as much trouble as I, and no one ever received as much love as you bestowed on me. Happily, I shall have heaven to avenge myself, for my Spouse in very rich and I shall draw from His treasures of love to repay you a hundredfold for all you suffered on my account.

St. Thérèse of Lisieux
