While you promote 2 kinds of sin, some "OK", and some "not OK", the Bible speaks differently:1 John 1:9 is the same as Acts 2:38. And 1 John 3:4-5 tells us which of the two types of sin it is that is taken out of our sin nature, leaving our nature clean/righteous. John 15:3.
Romans 6:5-12 KJV
5) For if we have been planted together in the likeness of his death, we shall be also in the likeness of his resurrection:
6) Knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin.
7) For he that is dead is freed from sin.
8) Now if we be dead with Christ, we believe that we shall also live with him:
9) Knowing that Christ being raised from the dead dieth no more; death hath no more dominion over him.
10) For in that he died, he died unto sin once: but in that he liveth, he liveth unto God.
11) Likewise reckon ye also yourselves to be dead indeed unto sin, but alive unto God through Jesus Christ our Lord.
12) Let not sin therefore reign in your mortal body, that ye should obey it in the lusts thereof.
Just "sin".
John 1:29 KJV
The next day John seeth Jesus coming unto him, and saith, Behold the Lamb of God, which taketh away the sin of the world.
No parsing of sins, just "sin".
Much love!
