Paul's Argument for the Unification of Jew and Gentile in Ephesus

In the traditions that ive come, faith through israel gets put to the wayside when it comes to talking about god's plan for redeeming humanity. I feel like there's a disrespect to the elder brother in and what i'm not trying to do is convert you to jewish. In an ultimate sense, the blessings that paul has been talking about are applicable to all believers in the messiah. We are this guy who changed the scope of the world regardless of how people feel about him. He kept on beating his drum every time he seemed to open his mouth. The kingdom isn't fully yet but jesus keeps telling us: 'The kingdom is here'
