[In confronting your friend about an addiction]
You are at a critical moment. Pay attention to the relationship. You are raising these issues because you love him. You are not confronting him for your benefit, but for his. Don’t let the person blame and defend. Stay on track, and don’t give in to your own frustrations or fears. Don’t play by the person’s defensive and attacking rules. Don’t take the insults or disrespect personally. Keep in mind that this person is most likely in danger. The fact that you have been hurt by his words and actions might not be the most important issue at this moment. Whatever disrespect you hear is ultimately disrespect toward God himself. You are witnessing a person who wants radical independence, and you know that any life other than that of faith and dependence on Christ is doomed to failure.
