Agape's object is always the concrete individual, not some abstraction called humanity. Love of humanity is easy because humanity does not surprise you with inconvenient demands. You never find humanity on your doorstep, stinking and begging.
Peter KreeftThere is no effective rational answer to the challenge: "But give me a reason why I should love someone who does not deserve it." Love is the highest thing. There can be no higher reason to justify it.
Peter KreeftIn this deed is my hope, not in the mere timeless fact that God is love. I am saved not by the beautiful Trinitarian life of God but by the gory death of God. I am saved not by the touching of the three Persons in Heaven but by the touching of this love on the Cross to my life.
