The essential message of the Act of Offeringis total submission to God which has been indicated in the scriptures of all the Abrahamic religions–Islam, Christianity, and Judaism:

a)      Hear, O Israel: The Lord our God is one Lord: And thou shalt love the Lord thy God with all thine heart, and with all thy soul, and with all thy might (Deu 6:4-5 KJV; Mark 12:31; Luke 10:27; Matt 22:37)–[Judo-Christian tradition].

b)      God did tempt Abraham, (…). Take now thy son, thine only son Isaac, whom thou lovest, (…); and offer him there for a burnt offering (…). And Abraham rose up early in the morning, (…): for now I know that thou fearest God, seeing thou hast not withheld thy son, thine only son from me. (…); And in thy seed shall all the nations of the earth [and not only one specific nation] be blessed because thou hast obeyed my voice (Gen 22:1,2,3,12,18).

c)      ‘Myson, I see in a dream that I shall sacrifice thee; consider, what thinkest thou?’ He said, ‘My father, do as thou art bidden; thou shalt find me, God willing, one of the steadfast.’ When they had surrendered, and he flung him upon his brow, We called unto him, ‘Abraham, thou hast confirmed the vision; even so We recompense the good-doers. This is indeed the manifest trial.’ And We ransomed him with a mighty sacrifice, and left for him among the later folk ‘Peace be upon Abraham!’ (Al-Qur’an  37:102-109; tr. A.J.Arberry, p. 460)–[Muslims].

d)      You can never attain righteousness until you spare, spend away, and consume of what you love (Al-Qur’an3::91)

Thus the essential message can be summed up as below:

The complete role model of submission to God is Abraham. He did not spare even his most beloved and direly essential asset, i.e. his only son, from God. Whosoever among all the nations of the earth completely obeys the Lord, shallbe blessed, because ‘submission to God’ brings harmony among the faiths and peace among all the people of God.
