If God as you understand him, has sinners in its universe, than maybe it could apply to him too?
I don't believe in sins myself, and God as I understand him doesn't have sinners.
What is a sin? A poor choice, a selfish choice in actions, or decisions?
I don't "understand" god in the sense that I agree with all of the things people have written and attribute to god or their favorite religion / god.
I do understand that it is in my power to direct my own actions, not in every circumstance, but in many. I think of that as my free will, restrained somewhat by my own limited physical and mental capacities. Meaning I can only do what I can do, can't do what I can't do. I might will myself to fly, but it's never happened and unless I grow wings, it won't etc. Albeit. sometimes external circumstances can negate our free will, but it's not a permanent state of being, meaning circumstances change and don't all occur in the same way for every person. Unless...a meteor. Okay, I'm digressing.
As far as god goes, I was raised as a Christian, but quickly learned to disappear sunday mornings as a kid to avoid going to sunday school etc. . Even as a kid I questioned how people blindly believed and obeyed things they were told without considering alternatives or the unintended consequences and contradictions of their religious beliefs.
Got alot of respect for that Jesus dude though, kind, intelligent, on a mission to help people, balls of steel when faced with a horrible punishment he didn't deserve. I don't think of him as god though, but certainly a fine example of a human being.
God, in the traditional Christian sense, is a contradiction and is likely a sinner, since he tells mankind he loves them, but if they don't love him back, he's gonna smite them. Kind of dickish behavior. So, yes, "god" (the guy from the bible) as I understand him would be a sinner.
I think it's possible human beings are a created hybrid species and our "god" was an explanation of the actions of other beings with more advanced technology who came to earth and fucked our women, thus creating mankind. We are escaped lab rats in that sense, with free will up to the limits of our individual capacities.
