Shalom.
I do read the epistles of Paul, yes.
What do you mean by
The only way that anyone can keep the law and be without sin is to be "In Christ".
Do you keep the law? What do you mean by be without sin?
The Spirit of God dwells in me.
Shalom.
Jacob
No one can do or keep God's law, Jacob. This is why Paul said, "There is none righteous, no, not one," Romans 3:10. If you want to be saved you are going to have to confess that you are a sinner, that is that your righteousness fails to meet the requirements of God's law.
Jesus said that he came into the world to save sinners. Paul confessed that he was "The chief of sinners" 1 Timothy 1:15.
