From the June 27 sermon on Luke 8:26-39:

Satan and demons are at war against God, angels, and Christians. Satan is the accuser, adversary, destroyer, deceiver, father of lies, tempter, murderer, evil one, and a real enemy. Jesus comes to liberate those who are taken captive in this cosmic battle. When he meets a man possessed by a multitude of demons, he exercises his authority over them. He casts them out of the man and into a large herd of pigs (unclean animals in the Old Covenant), condemning that region’s pagan way of life. The people are scared of Jesus, but the saved man obeys Jesus and stays behind to boldly preach his story about what Jesus did for him—converting many others after him.

"'And they came to Jesus and found the man from whom the demons had gone.' And here’s what he looks like now. 'Sitting at the feet of Jesus, clothed and in his right mind.' This guy’s sitting there, shaved, clean, bathed, dressed, notebook, pen, taking notes. What happened to this guy? He met Jesus. Jesus changes people. That’s just what he does. § See, no one’s beyond the grace of God. That’s why we don’t lose hope in anyone. Not 'in anyone,' let me state it correctly. We don’t lose hope for anyone. We don’t have hope in anyone. But we have hope for everyone because the hope is not in them. The hope is in Jesus. And it doesn’t matter where someone is. As long as they’re alive, there’s hope because Jesus could change them. He just does. Jesus changes, sometimes in an instant, the most unbelievable people who are seemingly beyond any hope."
