You do not entirely cease to become a sinner when you've accepted Jesus as your Lord and Savior.

I confess that yesterday I sadly fell twice to a former sin addiction of mine. I felt very sad and disappointed with myself, but more importantly that I had let down God. But I did repent and ask God for forgiveness. His Holy Spirit didn't leave me. I could still feel His peace at the end of the night.

There was actually a moment shortly after I fell a second time to that (former) sin habit, when I was in the bathroom, where I felt the presence of something scary moving close behind me. This was the first time in a long time that I felt anything scary. No doubt it was a demon that gained access to my home because of what I had done. That's how that works. I prayed to Jesus and cast out all demons / evil spirits from in and around me. And then as I was laying on my bed about to sleep, I said another prayer asking for forgiveness. That's when I had peace again and was able to sleep well. Thank you Lord.
