Perhaps the clearest and deepest meaning of brotherhood is the ability to imagine yourself in the other person's position, and then treat that person as if you were him or her. This form of brotherhood takes a lot of imagination, a great deal of sympathy, and a tremendous amount of understanding.
Perhaps the highest goodness attainable is a life of service to all mankind. Such an ideal is supported in nearly every page in the Gospels-the parables, the sermons, and the countless acts of service by our Lord Himself. The ideal is not limited to any particular kind of service, nor a given quantity of service. The ideal is accepting life itself as a trust to be used in the welfare of mankind. It is a life that is glad for the chance to be of any help, an attitude that 'service is the rent we pay for our own room on earth.' (Lord Halifax)
Agape means love for another self not because of any lovable qualities which he or she may possess, but purely and entirely because it is a self capable of experiencing happiness and misery and endowed with the power to choose between good and evil. The love of humans is thus more than a feeling, it is a state of the will.
