The honored Sages even say that the deep level of Abraham and Isaak,s
personal sacrifice acted as a kapparah (atonement)
for every sin that the nation of Israel ever made and ever will make.
Baha'u'llah said something very similar, although following the Qur'an he has Ismael rather than Isaac as the sacrifice:
"That which thou hast heard concerning Abraham, the Friend of the
All-Merciful, is the truth, and no doubt is there about it. The Voice
of God commanded Him to offer up Ishmael as a sacrifice, so that His
steadfastness in the Faith of God and His detachment from all else but
Him may be demonstrated unto men. The purpose of God, moreover, was to
sacrifice him as a ransom for the sins and iniquities of all the
peoples of the earth. This same honor, Jesus, the Son of Mary,
besought the one true God, exalted be His name and glory, to confer
upon Him. For the same reason was Husayn offered up as a sacrifice by
Muhammad, the Apostle of God.
No man can ever claim to have comprehended the nature of the hidden
and manifold grace of God; none can fathom His all-embracing mercy.
Such hath been the perversity of men and their transgressions, so
grievous have been the trials that have afflicted the Prophets of God
and their chosen ones, that all mankind deserveth to be tormented and
to perish. God's hidden and most loving providence, however, hath,
through both visible and invisible agencies, protected and will
continue to protect it from the penalty of its wickedness.
Ponder this in thine heart, that the truth may be revealed unto thee,
and be thou steadfast in His path." (Gleanings from the Writings of
Baha'u'llah, pp. 75-76.)
