Israel is no longer God's chosen people, you are right. When the Jews killed Jesus, (He let them, willingly - John 10) and Peter spoke on Pentacost and those 3,000 were baptized, they weren't all Israelites. Remember when they were speaking in tongues in the beginning of Acts 2 (tongues are languages that people can understand never in scripture does speaking in tongues mean some made up gibberish to generate revenue and enthusiasm) you can see how many nations were represented there. And then the Ethiopian eunic's baptism in Acts 8, Cornelius (a Roman centurion) and all his house, the Philippian jailer and his house all baptized. Israel no longer is significant in anyway other than it's history because they denied God and persecuted and killed every prophet that God sent them. Hence the parable about the owner of the vineyard having his workers and then finally his son killed when they were sent to collect.
