In my experience and understanding, I believe you are right.
I've heard all too long that God separates Himself from us when we sin, will fully or not. God knows I've had my battle with sin, I'm not ashamed to admit that, I will boast about my weakness!
But I have found that when I sought God, He was ALWAYS there. And I was always surprised because my mind tells me He had abandoned me because what I had done, which leads to more shame, more discouragement, less feeling worthy enough to seek Him.
The teaching of God abandons you to your sin leads man down a deeper hole.
Not that I condone or justify sin in any way.
But I believe some people think they are better fathers to their children than our Good Father Himself!
