If this person is genuinely a Christian, he does NOT have to *struggle* with any kind of unacceptable music. All he had to do it quit listening to garbage. Yes, just like that. Or if he had DVDs, or records, or whatever, all he had to do is destroy everything and throw it in the garbage bin.He told me when we met that he was struggling with it and knew he had to stop. So he told me that he was going to.
So the real issue is whether he is self-deceived about his Christianity and his salvation. If you both attend church it would be a good idea for you both to sit down with a pastor or elder and determine his true spiritual standing.
One can understand someone who has been smoking cigarettes for years having a hard time quitting this addiction *cold turkey*. But rap music?
Christians constantly talk about *struggling* with this and *struggling* with that. As though they have no power from God to quit whatever needs to be rejected.
