No difference. Just read 1 Cor 10 to understand HOW Israel failed.The bible doesn't say the "failed'.
They fell.
The result is they were cut off
Can you prove that it means loss of salvation? Of course you can't.Does broken off mean they were still saved?
Your posts have gotten way off track from the OP. Can you address the issue presented in the OP? If the gifts of 11:29 do NOT refer to the gifts that Paul clearly defined previously in Romans 5:15,16 and 6:23, then please show where Paul clearly excluded them from 11:29.No where in verse 29 does it say that eternal life is an irrevocable gift of God.

Your position has NOT been proven or demonstrated. All you've given is your opinion about what you think Paul meant. Nothing substantive.
I have provided very clear verses of what Paul described as gifts, and you've not refuted that, nor shown that those specific gifts were excluded from 11:29.
As to your last sentence that "no where in v.29 does it say that eternal life is an irrevocable gift from God", Paul defined eternal life as a gift, and you have NOT shown that Paul excluded THAT gift from v.29.
Further, you cannot demonstrate that Paul defined anything that God gave to Israel as a gift anywhere in Romans. Or even in any other book of the Bible.
Your position is merely an unsubstantiated opinion.
