Pure love is capable of great deeds, and it is not broken by difficulty or adversity. As it remains strong in the midst of great difficulties, so too it perseveres in the toilsome and drab life of each day. It knows that only one thing is needed to please God: to do even the smallest things out of great love — love, and always love. Pure love never errs. Its light is strangely plentiful. It will not do anything that might displease God. It is ingenious at doing what is more pleasing to God, and no one will equal it. It is happy when it can empty itself and burn like a pure offering. The more it gives of itself, the happier it is. But also, no one can sense dangers from afar as can love; it knows how to unmask and also knows with whom it has to deal.
