All that we experience in our life in Christ, beginning with salvation is by grace through faith. Paul shares with us what the Lord Jesus has done for us - both Jews and Gentiles. He has made us one - in Jesus there is neither Greek nor Jew (Galatians 3:28). The middle wall of separation, the law of commandments contained in ordinances has been abolished. We, both Jews and Gentiles are now one new man following the Lord Jesus and His Word for us. This has been made possible through the what Jesus accomplished on the Cross.
