This could be a angry declaration to a priest or preacher. "You sneak your way in while I'm sleeping" Could mean the preacher manipulated feelings of shame from painful experiences to convict his heart when he was weak and vulnerable and didn't know better. "Abuse my body while I'm sleeping" could mean the priest or preacher used his feelings to manipulate him into giving more money in the confessional. "Sell yourself to the people you're deceiving" Could be a reference to how the preacher or priest uses his or her eloquence to continue to manipulate the congregation. " Your conscience will bury you I'll dig the ditches." His truth will hit the preacher or priest's hard and I'll use your own weapon against you, conviction of your sin of lying.
