Phil, I reckon I see it a bit different than you as to Who is doing the work in us. We are God’s workmanship from beginning to end (Eph 2:10).
For it is God which worketh in you both to will and to do of his good pleasure (Php 2:13).
If we follow His leading of the Spirit, He fulfills the righteousness of the law in us; not by us (Rom 8:4).
What can we do? . . grow in grace, and in the knowledge of our Lord and Saviour Jesus Christ (2 Pet 3:18)
And this following armor consists completely of the word of God.
Finally, my brethren, be strong in the Lord, and in the power of his might (Eph 6:10).
Put on the whole armour of God, that ye may be able to stand against the wiles of the devil (Eph 6:11).
The inner Christ in me is experienced as He changes me from glory to glory.
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 (2 Cor 3:18). Again this is God’s perfect work in us, and the glory belongs to God.
My thoughts.
