Let me address each of your point in order.
That means when you read Isaiah 53 for example, that had him prophesying that the Messiah would be "pierced for our transgressions", avoid thinking, "Isaiah must have seen a cross and Jesus being our sin substitute, so that the divine exchange can take place". All these are later revelations.
My point about Acts 10 was to debunk the view that the Law of Moses was abolished at the cross. As far as the Jews are concerned, they continue to be zealous for the Law even in late Acts, until Paul was raised. Acts 21:20, Acts 22:12
Jesus was a minster only to the circumcision during his time on Earth. Matthew 15:24, Romans 15:8. Fig tree, vineyard and olive are always symbols in the Gospels referring to Israel and the Jews.
Some examples from the OT show that The fig tree is symbolic of Israel itself – It often symbolized the health of the nation both spiritually and physically. Hosea 9:10 says,
“When I found Israel, it was like finding grapes in the desert; when I saw your ancestors, it was like seeing the early fruit on the fig tree.”
Later, the Bible tells us of the glorious time when
“Judah and Israel lived in safety, every man under his vine and his fig tree, from Dan even to Beersheba, all the days of Solomon.” (1 Kings 4:25)
Guojing: "That means when you read
Isaiah 53 for example, that had him prophesying that the Messiah would be "pierced for our transgressions", avoid thinking, "Isaiah must have seen a cross and Jesus being our sin substitute, so that the divine exchange can take place". All these are later revelations."
I don't see why Dispensationalists are so hostile to OT prophecy. I have no idea whether Isaiah saw a cross but Isaiah 53 foretells several things about the life of Jesus and its significance.
It tells us that this Person will be "pierced," just as the hands, feet and side of Jesus were pierced. It tells us that this Person will be "cut off from the land of the living" and make His grave with "the rich." We know that Jesus was buried in a tomb that belonged to Joseph of Arimathea, a rich man. Even more incredibly, it tells us that this Person "bore our suffering." Further, this Person is the "righteous servant" who will "bear" the "iniquities" of "many." This is repeated at the end, that"he bore the sin of many" and "made intercession." In a line that must have seemed contradictory at the time, it says that after suffering to death, this person will "see the light of life." He will be resurrected.
Isaiah tells us that this coming Messiah will die, willingly, and that He will return to life. The prophet not only tells us crucial details about His life, but foresees the significance that Christians will see in the life, death, and resurrection of Jesus Christ.
Isaiah 53 New International Version (NIV)
53 Who has believed our message
and to whom has the arm of the Lord been revealed?
2 He grew up before him like a tender shoot,
and like a root out of dry ground.
He had no beauty or majesty to attract us to him,
nothing in his appearance that we should desire him.
3 He was despised and rejected by mankind,
a man of suffering, and familiar with pain.
Like one from whom people hide their faces
he was despised, and we held him in low esteem.
4 Surely he took up our pain
and
bore our suffering,
yet we considered him punished by God,
stricken by him, and afflicted.
5 But
he was pierced for our transgressions,
he was crushed for our iniquities;
the punishment that brought us peace was on him,
and by his wounds we are healed.
6 We all, like sheep, have gone astray,
each of us has turned to our own way;
and the Lord has laid on him
the iniquity of us all.
7 He was oppressed and afflicted,
yet he did not open his mouth;
he was led like a lamb to the slaughter,
and as a sheep before its shearers is silent,
so he did not open his mouth.
8 By oppression[
a] and judgment he was taken away.
Yet who of his generation protested?
For he was cut off from the land of the living;
for the transgression of my people he was punished.[
b]
9 He was assigned a grave with the wicked,
and with the rich in his death,
though he had done no violence,
nor was any deceit in his mouth.
10 Yet it was the Lord’s will to crush him and cause him to suffer,
and though the Lord makes[
c] his life an offering for sin,
he will see his offspring and prolong his days,
and the will of the Lord will prosper in his hand.
11 After he has suffered,
he will
see the light of life[
d] and be satisfied[
e];
by his knowledge[
f] my
righteous servant will justify many,
and he will
bear their iniquities.
12 Therefore I will give him a portion among the great,[
g]
and he will divide the spoils with the strong,[
h]
because he poured out his life unto death,
and was numbered with the transgressors.
For he bore the sin of many,
and made intercession for the transgressors.
