A covenant is a contract. You can't make a one way contract.

G-d loves all of mankind not just the Jews. Israel is called G-d's "first born son" but He has many children. All of us are His children.

The covenant with the Jews is to bring the knowledge of Torah and G-d to the rest of the world. We are a nation of priests. When the messiah comes there will be worldwide knowledge of G-d and worldwide peace. . .

not just peace and knowledge for the Jews.

G-d formed a covenant with the Jews because most of mankind fell into idolatry. That will change one day. Do not think of yourself as excluded if you are not Jewish. Whereas Xianity says you must be a Xian for their god to love you, Judaism knows that G-d loves all of His creation.
