Israel Falls in Acts but is not Counted "Out" until Acts 28

      In boxing after a fighter falls down, the referee begins a ten-second count, giving the boxer a chance to recover and get back on his feet.  Boxers get knocked down fairly often but are able to get back up before being counted out and continue the fight.  Sometimes the boxer that gets knocked down ends up getting back up (before the 10 count) and goes on to win the fight.  Many Acts 2 and Mid Acts dispensationalists argue that since Israel has fallen by the time of Paul writing Romans 11 that God did not allow Israel another opportunity to repent and receive another offer of the kingdom. 

Romans 11:11-12 states:

 [11] I say then, Have they stumbled that they should fall? God forbid: but rather through their fall salvation is come unto the Gentiles, for to provoke them to jealousy.
[12] Now if the fall of them be the riches of the world, and the diminishing of them the riches of the Gentiles; how much more their fulness?

I agree that Israel has fallen by the time Romans 11 is written; however, I would argue that they have not been counted out of the fight to use boxing terminology.   In boxing terminology God has not counted to 10 in Romans 11.  It appears God does not say "ten" until after Paul preaches one final time to Israel's leaders in Acts 28.  If Paul thought Israel had been counted out, then why does he pray for their National Salvation in Romans 10:1.  In my opinion Romans 11:23 should make it clear that Israel has not been counted out of the fight at the time of Paul writing Romans.  Romans 11:23 states:

[23] And they also, if they abide not still in unbelief, shall be graffed in: for God is able to graff them in again.

The very people that had fallen can get back up by not abiding in unbelief according to Romans 11:23.  The unpardonable sin is not charged to Israel until after they reject the kingdom for the final time at Acts 28.  Once Bible believers understand this, then they can quit making excuses as to why Paul acted the way he did during the book of Acts.  In Acts Paul preached a pure grace message to the Gentiles called the gospel of the uncircumcision.  However Paul recognized for Israel that their kingdom offer was still on the table, so he never once called out believing Jews for observing ceremonial ordinances of the Law because those things would continue as memorials when the Kingdom is setup.  For example, study Ezekiel 40 through 48.  Remember, if Israel had repented in Acts, then those same people would see the return of Christ and the setting up of the Kingdom (Acts 3:19-21).
