Piper: Can a Pastor, who has sinned sexually, be restored?

Any material (either pictures or words or video, etc) that is sexually explicit that is designed in any way (whether primarily or even secondary or tertiary, or even accidentally) to produce sexual arousal in viewers, or any non-sexually explicit material that can also be used to produce sexual arousal (but not necessarily at the fault of the creator).

To live a life of self-control and complete honesty and transparency and authenticity and to free from bondage to my addictive behaviors of viewing pornography and masturbation. This means to not look on anything on purpose (or accidentally on purpose) that could be considered pornography and definitely absolutely no masturbation.
