There is only one power which can from within undermine egoism at the root, and really does undermine it, namely love, and chiefly sexual love. The falsehood and evil of egoism consists in the exclusive acknowledgement of absolute significance for oneself and in the denial of it for others. Reason shows us that this is unfounded and unjust, but simply by the facts love directly abrogates such an unjust relation, compelling us not by abstract consciousness, but by an internal emotion and the will of life to recognize for ourselves the absolute significance of another. Recognizing in love the truth of another, not abstractly, but essentially, transferring in deed the centre of our life beyond the limits of our empirical personality, we by so doing reveal and realize our own real truth, our own absolute significance, which consists just in our capacity to transcend the borders of our factual phenomenal being, in our capacity to live not only in ourselves, but also in another.
The central fact of biblical history, the birth of the Messiah, more than any other, presupposes the design of Providence in the selecting and uniting of successive producers, and the real, paramount interest of the biblical narratives is concentrated on the various and wondrous fates, by which are arranged the births and combinations of the 'fathers of God.' But in all this complicated system of means, having determined in the order of historical phenomena the birth of the Messiah, there was no room for love in the proper meaning of the word. Love is, of course, encountered in the Bible, but only as an independent fact and not as an instrument in the process of the genealogy of Christ. The sacred book does not say that Abram took Sarai to wife by force of an ardent love, and in any case Providence must have waited until this love had grown completely cool for the centenarian progenitors to produce a child of faith, not of love. Isaac married Rebekah not for love but in accordance with an earlier formed resolution and the design of his father. Jacob loved Rachel, but this love turned out to be unnecessary for the origin of the Messiah. He was indeed to be born of a son of Jacob - Judah - but the latter was the offspring, not of Rachel but of the unloved wife, Leah. For the production in the given generation of the ancestor of the Messiah, what was necessary was the union of Jacob precisely with Leah; but to attain this union Providence did not awaken in Jacob any powerful passion of love for the future mother of the 'father of God' - Judah. Not infringing the liberty of Jacob's heartfelt feeling, the higher power permitted him to love Rachel, but for his necessary union with Leah it made use of means of quite a different kind: the mercenary cunning of a third person - devoted to his own domestic and economic interests - Laban. Judah himself, for the production of the remote ancestors of the Messiah, besides his legitimate posterity, had in his old age to marry his daughter-in-law Tamar. Seeing that such a union was not at all in the natural order of things, and indeed could not take place under ordinary conditions, that end was attained by means of an extremely strange occurrence very seductive to superficial readers of the Bible. Nor in such an occurrence could there be any talk of love. It was not love which combined the priestly harlot Rahab with the Hebrew stranger; she yielded herself to him at first in the course of her profession, and afterwards the casual bond was strengthened by her faith in the power of the new God and in the desire for his patronage for herself and her family. It was not love which united David's great-grandfather, the aged Boaz, with the youthful Moabitess Ruth, and Solomon was begotten not from genuine, profound love, but only from the casual, sinful caprice of a sovereign who was growing old.
Sometimes, oftentimes, people hold on to someone they love for self – because it's what they want; in rare cases, a person, who sincerely knows the meaning of love, which is sacrifice, loves enough to say goodbye and to walk away. They do it because they love someone enough to allow them to move on without them or to not be torn in multiple directions, which causes confusion, or because they feel that is their only choice.Loving like that is doing for another and denying self. It is sacrifice.It takes tremendous strength and the cost is loss and heart-ache but it's a price the rare are willing to pay because they truly love that much.
