First, God made his curse in the Garden for as long as man shall live with no option to lift it. That in itself makes any savior a latter-day innovation.
Second, God never states his conditions for lifting the curse. This was simply UNKNOWN to the OT Jews. Jewish messiah was not supposed to be crucified. Jews did not crucify. No one recognized Jesus as the messiah because he doesn't fit what the Jewish Bible says about the messiah, yet you find Jesus all over it! Maybe you should teach the Jews how to read their of scriptures...
Third, you say by dying on the Cross, Christ "allowed" God to lift the curse! Wow! His death allowed God to do something. God had to wait for Jesus before he would be "allowed" to save the elect. Wow! Interesting "theology'.
There is a rebalancing and restoration of order that began with the death and resurrection of Jesus Christ.
No, God was restoring order already in Genesis 6 by drowning the whole world and sparing but a select few and then making a Covenant with every living creature on Noah's Ark (mostly animals!) "for all generations." There is no hint of any need or "allowance" for further restoration, or of God doing what he wouldn't allow Abraham to do to his son.
It comes down again to personal faith....
Your are not kidding!
