We humans are full of imperfections. For example, someone say something harsh about me and I lose my peace, even just momentarily. And we have inappropriate fleeting thoughts at times. If you consider these imperfections as sins, then they are unintentional ones. I believe that the Lord fully understands our human nature and that we won't be perfect until we get to heaven. It's good to know that we can be imperfect and be innocent, and that we'll be like the Lord after we see him.
