We never left G-d. The Book of Deuteronomy tells us there will be no further revelations, so we are doing precisely what G-d told us he wants us to do. If what you mean is when will the Jews acknowledge Jesus as a god, then never.
they all are one god
Yes, that is probably a fair statement to make, but not all Jews believe that, and in fact, not all Jews believe in God.
People of all races are sinful in nature and naturally do rebel against God. It makes no difference if they are God's chosen people or not. God did not choose them because they were perfect or particularly obedient. Not all Jews are unfaithful to God, however, just as not all non-Jews follow God.
The Jewish God is considered the Father of all. Just like any other religion, Jews show honor and respect to their God.
Jews were sent into a death camp because Hitler had no mercy to hold back and kill all Jews. He belived that everyone should worship him as there god. He also belived that Jews were the dirtiest race and hated how they celebrated there holidays.
Some do, some don't. Not all Jews are loyal to Jewish tradition.
They all believe in one God.
No; all who are in the memory of God will be brought back to life as a human. (John 5:28,29)
Some Jews are Christians but most are not. It is because Christians believe that Jesus is the son of God, the Messiah, who died as the lamb of God, a sacrifice for all who believe. Jews do not believe this.
Because Allah is a god that only Muslims believe in. From the Jewish perspective, the name 'Allah' is just the Arabic name for 'HaShem' (The Creator) and is used by many Jews who came from Arab countries.
The anit-christ is coming for any and everybody who is of God. Specific religion doesn't matter. He's coming to kill and pull away all of God's people.
From the Jewish perspective, all people from all nations will have a place in the world to come. There are different paths to HaShem for different people, Judaism is the path for Jews.
