I agree that we are not lawless.
Even though we are not under the law (Romans 6:14) are dead to the law (Romans 7:4, Galatians 2:19) and are delivered from the law (Romans 7:6); this does not make us lawless.
For we are governed by the law of faith (Romans 3:27).
And also, the law of the Lord is written on our hearts and in our minds (Hebrews 8:8-10, Hebrews 10:16).
We have been given the Spirit, who sheds abroad His love in our hearts (Romans 5:5) so that we fulfill the law (Romans 13:8-10, Galatians 5:14, 1 John 5:3, 2 John 1:6, Romans 8:4). For this love is not in word or in tongue only; but in deed and in truth (1 John 3:17-18). It is the fruit of the Spirit, against which there is no law (Galatians 5:22-23).
Therefore the scripture stands true:
Rom 3:21, But now the righteousness of God without the law is manifested, being witnessed by the law and the prophets;
For we receive the Spirit by faith (Galatians 3:14) and not by the keeping of the law (Galatians 3:1-9).
We are therefore no longer condemned by the law from the outside, as being written on tablets of stone. But we are governed by it from the inside, as being written on fleshy tables of human hearts.
It is the love of God through obedience to the Holy Spirit that fulfills the righteousness of the Lord within us (Romans 8:4).
It is not through attempting to keep a set of do's and don'ts that we obtain our obedience as NT believers. Rather, through abiding in the vine, we draw up nourishment from the vine; and this results in holy living because the sap is holy.
