Without the law we are righteous in the sight of God through faith in Christ, because God's grace is also opposed to the law.
God's grace, and God's law are arch enemies one with another.
Correction please, it is 'just you' and not more of 'abiding' in CHRIST's words/teachings and through the Apostles of the New Covenant in you.
First of all, as Apostle Paul said the actual benefits of the 'Law of the Letter', that without that 'Law' that acted as a 'custodian' first, he wouldn't have known what he have sinned against GOD and fellow men, therefore then in order to come under Grace and Truth/Gospel of GOD through CHRIST, now forgiven of all past failed battles against sin and death, by now having faith in CHRIST.
Since henceforth from death now alive and led to have 'faith' in CHRIST, as our Savior and Redeemer, only 'by Grace through faith, the free gift of GOD', have been freely welcomed in, introduced us to HIS SON, as our MASTER and of HIS 'house' now.
And so we are no longer under the 'Law' but under 'Grace'. But the MASTER/CHRIST of the 'house' also brought the 'Truth' according to the Gospel of John, 'Grace and Truth'. Therefore the truth of the New Covenant instructs us to hear HIS words/teachings and do/practice them and become as 'wise builders'. And also 'abide' in them and love according to them and that truth shall set us free. When the MASTER sets us free, indeed we are free.
GOD's Grace is not oppose to the 'Law', but according to Apostle Paul, 'Grace upholds the Law'. Actually the weak carnal/flesh's passions and desires opposed GOD's Law from the beginning.
What a 'babes in CHRIST' of carnality 'testimony', to testify Grace and the Law are arch enemies?
Galatians chapter 5, helps us 'grow up' to know and live faithfully and not perish once again, who is truthfully the 'arch enemy' of GOD and HIS SPIRIT and that dishonors HIS SON, even LORD JESUS CHRIST, MASTER of the 'redeemed' house of GOD from slavery.
May GOD the FATHER of our LORD JESUS CHRIST forgive you and bless you.
