" It is characteristic of mature love that it calls into play all man's potentialities; it engages the whole man, so to speak. Contact with the visible manifestations of God's love can awaken within us a feeling of joy born of the experience of being loved. But this encounter also engages our will and our intellect. Acknowledgment of the living God is one path towards love, and the “yes” of our will to his will unites our intellect, will and sentiments in the all- embracing act of love. But this process is always open-ended; love is never “finished” and complete; throughout life, it changes and matures, and thus remains faithful to itself. "
― Benedict XVI , God Is Love: Deus Caritas Est
