Yes, Israel was to be the chosen nation with the blessings but they rejected Jesus Christ and Gentiles were welcomed into the newly forming Church (Christianity)...And if some of the branches were broken off and you being a wild olive tree (gentiles) were grafted in among them, and with them became a partaker of the root and fatness of the olive tree (Jew) do not boast against the branches . But if you boast remember that you do not support the root but the root (Jesus)supports you. You will then say branches were broken off that I might be grafted in...Romans 11:17-19... The only religion that is like a close relative to Christianity is Judism all other religions are not based on the true living God of Israel and are false religions that got their beginnings from the worship of idols or demons....The word religion means the belief in and worship of a God or gods...Even in Christianity there are various sects that claim to be Christian but they are not based on the redeeming blood of Jesus Christ and they emphasize works over faith or some other theory that is not in the Holy Bible which is our road map for all of life's answers... Your Word ( the Holy Bible) is a lamp unto my feet and a light to my path..Psalm 119:105
