Take away from love the fullness of self surrender, the completeness of personal commitment, and what remains will be a total denial and negation of it.
Pope John Paul IIReal love is demanding. I would fail in my mission if I did not clearly tell you so. For it was Jesus - our Jesus himself - who said: 'You are my friends if you do what I command you'. Love demands effort and a personal commitment to the will of God. It means discipline and sacrifice, but it also means joy and human fulfilment.
