I’m well aware of the conflict. I experience it too. But, careful, in saying a new creature created in Christ sins...meaning sin will carry on into the new creation. To imply all remains under Adam instead of under Christ rule. God says sin will be no more in the new creation; no more raging seas. Peace.
Ephesians 2:8-12
[8] For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: [9] Not of works, lest any man should boast. [10] For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them. [11] Wherefore remember, that ye being in time past Gentiles in the flesh, who are called Uncircumcision by that which is called the Circumcision in the flesh made by hands; [12] That at that time ye were without Christ, being aliens from the commonwealth of Israel, and strangers from the covenants of promise, having no hope, and without God in the world:
Philippians 3:17-21
[17] Brethren, be followers together of me, and mark them which walk so as ye have us for an ensample. [18] (For many walk, of whom I have told you often, and now tell you even weeping, that they are the enemies of the cross of Christ: [19] Whose end is destruction, whose God is their belly, and whose glory is in their shame, who mind earthly things.) [20] For our conversation is in heaven; from whence also we look for the Saviour, the Lord Jesus Christ: [21] Who shall change our vile body, that it may be fashioned like unto his glorious body, according to the working whereby he is able even to subdue all things unto himself.
Hebrews 11:15-16
[15] And truly, if they had been mindful of that country from whence they came out, they might have had opportunity to have returned.(to the old) [16] But now they desire a better country , that is, an heavenly: wherefore God is not ashamed to be called their God: for he hath prepared for them a city.
Philippians 2:4-5
[4] Look not every man on his own things, but every man also on the things of others. [5] Let this mind be in you, which was also in Christ Jesus:
—how can you look on the things of others while you mind what you came out of and left behind as if you desire to return to the old? If you are always minding the flesh instead of mindful of the power and Spirit of God.
Consider: your OP shows there is no forgiven sins (future) in a new creature...all has been made new in Christ. Don’t dirty it by calling what is created in Christ unclean.
