Gods will on all the earth is to save as many as possible from the final judgment that must take place.
His Righteousness is found in his mercy and long suffering. His word are also his promises that will not pass until all is fulfilled.
What started in Israel will end in israel.
Scripture tells us that its not the outward appearance but the inward that determines a jew the same can be said of a Christian.
It's the heart of the matter. ..as the lord always points to the heart.
Now to answer your question as you say the spirit won't let me directly.....will all Israel be saved .....yes....are all jews Israel..... no.
The same can be said for Christians can it not?
This goes right along with......Love the Lord your God with all your heart, mind, and might. And love your neighbor as yourself.
the fulfillment of the all the commandments.
We must stop thinking all jews are all the same. Jesus clearly exposed this when he came the first time. That has been my message to all that will hear it.
btw you didn't answer my question which is "What is God's plan for those in Israel who go against his will? ". It's difficult to get a direct answer to this question for some reason.
