Apostle Paul’s argument is basically on the aspect that the following of the law of God the Father must be done along with the thorough knowledge of God’s righteousness in Jesus Christ. This implies that Paul wants to convey that all the qualities of Jesus Christ (like humility, love, kindness, generosity, forgiveness, etc.) must be imbibed and followed by the believers and followers of God apart from the obeying of the existing Law of God.
