A couple came to our church. Because they moved, they didn’t continue coming to our church. Later, the wife went to practice Qigong, and the evil spirit possessed her. They asked the preacher in our church to cast out the evil spirit, the evil spirit was cast out but came back again. Later the preacher told her to commit her life to the Lord in baptism. After she was baptized, she received the Holy Spirit and the evil spirit never came back again. Her husband was baptized at the same time. I knew her husband many years ago.
