It seems that you both asked and then answered the question. {lol} Indeed
no one is without sin, but under the Law all kinds of sines were listed.
Then a Lamb's Blood was used to address a forgivness of them; for one year
as I understand it.

It is in the Blood of Christ that we put faith and seek to have our sins forgiven. The Law as a teacher has lead to Christ, but to be in Christ is really a new way of looking at this sinful nature, and we who are in the flesh must learn to live by the spirit.

I smoke and seek to use God's Spirit to help me fight this habit. It is more than just an act, I have made it a practice. To have God's Spirit
I can not keep doing this. And it is possible to live without smoking.

I do wish this was my only sin, but there are others, and I feel each one is what God sees. Thus it is my faith, and hope, along with my growing Love that I understand all that you have said.

I do hope we can talk more about this. And look to hear more from you.
