"Does a wall of sin build up over time between us and God?"

I felt sick while watching a movie scene, so I walked out. What was that exactly? Grieving or quenching the Spirit? Or was it my own spirit provoked within me? Or my conscience? And what if I had remained in the theater? Would my ministry effectiveness be blocked until I confess it? Does a wall build up between us and God when we sin? What are your thoughts on the spiritual disciplines?
