Sacrificial love is self-sacrifice with the pure motivation to alleviate the suffering of others. This supreme love is suffering love, love that requires involvement in the knotty problems of the world, love that bears with the failings and weaknesses of others, love that is committed to helping others regardless of the cost. We have the example of Jesus Christ, who offered his life to redeem sinful humanity, and Moses, who risked his life before Pharaoh for the sake of his people. We have the example of the bodhisattva, who vows to devote himself to save all beings and to accept their sufferings as his own. He regards his own happiness as incidental to the happiness of others. He does not claim the merit of his spiritual progress for himself, but offers it for the liberation of others.
Greater love has no man than this, that a man lay down his life for his friends.
Christianity. John 15.13
The position of love can be established when one sacrifices oneself and gives oneself for others. Thus sacrifice accompanies love.
Unification Church. Sun Myung Moon, 9-11-72
A man should share in the distress of the community, for so we find that Moses, our teacher, shared in the distress of the community.
Judaism. Talmud, Taanit 11a
The believer who participates in human life, exposing himself to its torments and suffering, is worth more than the one who distances himself from its suffering.
Islam. Hadith of Ibn Majah
It is not always physical bravery that counts. One must have the courage to face life as it is, to go through sorrows and always sacrifice oneself for the sake of others.

Kipsigis Saying (Kenya) We who are strong ought to bear with the failings of the weak, and not to please ourselves; let each of us please his neighbor for his good, to edify him. For Christ did not please himself; but, as it is written, “The reproaches of those who reproached thee fell on me.”
Christianity. Romans 15.1-3
Mencius said, “Those who are morally well-adjusted look after those who are not; those who are talented look after those who are not. That is why people are glad to have good fathers and elder brothers. If those who are morally well-adjusted and talented abandon those who are not, then scarcely an inch will separate the good from the depraved.” by http://www.unification.net/ws/theme139.htm
