We all value biblical advice from our elders, the first ones to whom we turn for counsel. Jeremy Walker outlines the kind of answer he might give to a question received at the chapel door.
‘I want to be free from porn but feel trapped. I repent, resist, then give in. Is my desire to be free realistic? Do I just need to get married?’
I am very grateful that God has given you the humility and courage to speak about this. It is hard to fight these battles alone. The shame associated with this sin means we easily become isolated, and that is dangerous.
You are entering a hard battle. A sinful attachment to pornography often produces just the kind of guilt you describe and the cycle of sin that you identify. Sinful sexual indulgence may actually produce physical changes, literally ingrained mental habits.
