Unfortunately the site closed so I may have lost the first part of this response (and no rejoicing, lol), and time is waning so will post what I have left, I hope, and probably continue this later:
Not according to Scripture.
Hebrews 10:1-4
King James Version (KJV)
1 For the law having a shadow of good things to come, and not the very image of the things, can never with those sacrifices which they offered year by year continually make the comers thereunto perfect.
2 For then would they not have ceased to be offered? because that the worshippers once purged should have had no more conscience of sins.
3 But in those sacrifices there is a remembrance again made of sins every year.
4 For it is not possible that the blood of bulls and of goats should take away sins.
I would remind you that the Law was the last Economy prescribed for Israel (which extends to all proselytes) prior to the establishment of the New Covenant.
The primary point being that the death of animals...cannot take away sins.
That is contrasted with Christ's sacrifice, so we conclude without a doubt...Abraham's transgression were not redeemed until Christ died.
That is why the Writer points out the difference between the First and New Covenants, and he does that repeatedly through the Epistle.
Again...
Hebrews 12:22-24
King James Version (KJV)
22 But ye are come unto mount Sion, and unto the city of the living God, the heavenly Jerusalem, and to an innumerable company of angels,
23 To the general assembly and church of the firstborn, which are written in heaven, and to God the Judge of all, and to the spirits of just men made perfect,
24 And to Jesus the mediator of the new covenant, and to the blood of sprinkling, that speaketh better things than that of Abel.
Now, to ensure that there is no question that the New Covenant is superior to all others that came before it (and I mean superior in that it fulfills all Covenants in it's establishment), the Writer, hence the Holy Ghost...goes all the way back to the sacrifice offered by Abel.
This covers all of human history in regards to atonement for sin through the very penalty sin reaps...death:
Genesis 4
King James Version (KJV)
4 And Abel, he also brought of the firstlings of his flock and of the fat thereof. And the Lord had respect unto Abel and to his offering:
You will need to address the Scripture provided already in order to support your denial of this Doctrine, which as I said, is basic to the Old Testament Economies, as well as highlighted in Hebrews for their inadequacies in regards to remission of sin.
I would rather not have to repost the same Scripture over and over without response, but, if that is necessary so be it.
Understanding the theme of Perfection in Hebrews will help you understand this better. Those sacrifices, from Abel unto Christ's...could not take away sins. And the taking away is a reference to the penalty owed for sin. Abraham died with his sin debt. Being justified secured his eternal destiny, but that did not take away his guilt and the penalty for that sin.

that this is equivalent to his sins being forgiven.

Contrary to what you seem to claim, his sins were not temporarily forgiven because he offered up a substitutionary animal for atonement,
