The NT without Paul would be that no Christian could say that Israel was condemned and judged with spiritual blindness, because of unbelief in Jsus, and declared guilty with the Gentiles (Rom 11:32). Because of that G-d can have mercy upon all. Because of what Paul wrote Christians main mission in life would be the conversion of the Jew and Gentile alike. The Mosiach is, in essence, the coming Anti-Christ.
