If we can still sin now, it proves one thing, the law is yet to be written in our hearts. There is no process involved.
Of course there is a process ... the NT describes it ... and labels it
GROWTH.
What do you think the NT writers mean when they speak of
GROWING IN CHRIST ?
2 Peter 3:18 But
grow in the grace and knowledge of our Lord and Savior Jesus Christ. To him be the glory both now and to the day of eternity. Amen.
Philippians 1:9 9 And it is my prayer that
your love may abound more and more, with knowledge and all discernment, 10 so that you may approve what is excellent, and so be pure and blameless for the day of Christ, 11 filled with the fruit of righteousness that comes through Jesus Christ, to the glory and praise of God.
Hebrews 6:1 Therefore let us leave the elementary doctrine of Christ and
go on to maturity, not laying again a foundation of repentance from dead works and of faith toward God, ...
1 Peter 2:2-3 Like newborn infants, long for the pure spiritual milk, that by it you may
grow up into salvation — if indeed you have tasted that the Lord is good.
Ephesians 4:15 Rather, speaking the truth in love, we are to
grow up in every way into him who is the head, into Christ, ...
Hebrews 5:12-14 For though by this time you ought to be teachers, you need someone to teach you again the basic principles of the oracles of God. You need milk, not solid food,
for everyone who lives on milk is unskilled in the word of righteousness, since he is a child. But
solid food is for the mature, for those who have their powers of discernment trained by constant practice to distinguish good from evil.
Philippians 1:6 And I am sure of this, that
He who began a good work in you will bring it to completion at the day of Jesus Christ.
1 Corinthians 3:1-2 But I, brothers, could not address you as spiritual people, but as carnal,
as infants in Christ.
I fed you with milk, not solid food, for you were not ready for it. And even now you are not yet ready, for you are still carnal.
