So first show me where Abraham was told of Christ, His death, and His resurrection...that he might believe on Christ.
Then explain how Abraham had revealed to him something Paul teaches in numerous places was not revealed to men in past Ages.
Here is another passage that shows that:
Romans 16:25-26
King James Version (KJV)
25 Now to him that is of power to stablish you according to my gospel, and the preaching of Jesus Christ, according to the revelation of the mystery, which was kept secret since the world began,
26 But now is made manifest, and by the scriptures of the prophets, according to the commandment of the everlasting God, made known to all nations for the obedience of faith:
Here's another:
Colossians 1:25-26
King James Version (KJV)
25 Whereof I am made a minister, according to the dispensation of God which is given to me for you, to fulfil the word of God;
26 Even the mystery which hath been hid from ages and from generations, but now is made manifest to his saints:
This...
Galatians 3:22-25
King James Version (KJV)
22 But the scripture hath concluded all under sin, that the promise by faith of Jesus Christ might be given to them that believe.
23 But before faith came, we were kept under the law, shut up unto the faith which should afterwards be revealed.
24 Wherefore the law was our schoolmaster to bring us unto Christ, that we might be justified by faith.
25 But after that faith is come, we are no longer under a schoolmaster.
...not only doesn't show Abraham was believing in the Risen Savior, but states just the opposite.
The name Jesus Christ would not be called upon until there was a man named Jesus Christ, Who would go to the Cross and die in the stead of sinners.
Secondly, we see that faith in Christ is distinguished from the Age of Law, and not present in it. Faith in Christ follows the Age of Law, when men were kept under the Law.
This is true, but he did not have specific revelation. He trusted God that God would bless all families of the earth, and this through his seed. He understood that in a physical sense, thus knew that if he slew Isaac, God, of necessity, would have to resurrect him, so His promise would be fulfilled.
But, what Abraham did not receive was the Promises themselves. He received promise (when it was given, but did not receive them (in the sense of being fulfilled, though he has now received them after his death):
Heb 11:13
¶
These all died in faith, not having received the promises, but having seen them afar off, and were persuaded of them, and embraced them, and confessed that they were strangers and pilgrims on the earth.
Heb 11:39
¶
And these all, having obtained a good report through faith, received not the promise:
Heb 11:40
God having provided some better thing for us, that they without us should not be made perfect.
Sorry, Bibliegateway has crashed (honest, I didn't do it...), so using Blue Letter.
The bottom line is that faith in the Old Testament was general, not specific to Christ and His Death and Resurrection. The disciples themselves did not expect him to die, but expected a physical fulfillment of the Prophecy. Here is an example:
Luk 24:17
¶
And he said unto them, What manner of communications are these that ye have one to another, as ye walk, and are sad?
Luk 24:18
¶
And the one of them, whose name was Cleopas, answering said unto him, Art thou only a stranger in Jerusalem, and hast not known the things which are come to pass there in these days?
Luk 24:19
¶
And he said unto them, What things? And they said unto him, Concerning Jesus of Nazareth, which was a prophet mighty in deed and word before God and all the people:
Luk 24:20
And how the chief priests and our rulers delivered him to be condemned to death, and have crucified him.
Luk 24:21
But we trusted that it had been he which should have redeemed Israel: and beside all this, to day is the third day since these things were done.
The Mystery was not revealed until the Comforter was sent. Abraham did not trust in a Risen Savior prior to his death.
God bless.
