Ughhh. Spoiler that shit, anon!
Paul addresses the tension between law and grace often. His stance is that the new covenant is one of grace, in which the law is also fulfilled, as promised in Jeremiah, by writing the law of God in hearts and in minds. But this is only possible in us because Christ has perfectly fulfilled the law in our behalf and makes us new creatures in the Holy Spirit.
Romans 6:14–23 (KJV): For sin shall not have dominion over you: for ye are not under the law, but under grace.
15 What then? shall we sin, because we are not under the law, but under grace? God forbid. 16 Know ye not, that to whom ye yield yourselves servants to obey, his servants ye are to whom ye obey; whether of sin unto death, or of obedience unto righteousness? 17 But God be thanked, that ye were the servants of sin, but ye have obeyed from the heart that form of doctrine which was delivered you. 18 Being then made free from sin, ye became the servants of righteousness. 19 I speak after the manner of men because of the infirmity of your flesh: for as ye have yielded your members servants to uncleanness and to iniquity unto iniquity; even so now yield your members servants to righteousness unto holiness. 20 For when ye were the servants of sin, ye were free from righteousness. 21 What fruit had ye then in those things whereof ye are now ashamed? for the end of those things is death. 22 But now being made free from sin, and become servants to God, ye have your fruit unto holiness, and the end everlasting life. 23 For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord.
I agree. That is unquestionable.
But my Orthodox Christian tradition takes a holistic view of the life in Christ, which requires constant vigilance and repentance. Christianity in the East was not dominated by lawyers, but by monastics: it’s why many of the controversies of the West do not compute. Western controversies over either/or are typically both/and for the Orthodox.
Christian Theology has a technical term for absolutely everything, fren!
Salvation is Union with Christ and being conformed to His likeness (which is the true destiny of humanity). Any doctrine of salvation that is not about being transformed ”from glory to glory” is not Christian salvation at all.
2 Corinthians 3:17–18 (KJV): Now the Lord is that Spirit: and where the Spirit of the Lord is, there is liberty. 18 But we all, with open face beholding as in a glass the glory of the Lord, are changed into the same image from glory to glory, even as by the Spirit of the Lord.
