Last sermon (May 31,1999 in Okmulgee, OK) by Bishop Oscar Moore, IPHC . "This was recorded on a cassette tape. The tape was purchased by Hazel Morris, mother of Jerry Morris. Jerry had the recording encoded as an MP3 file and is now sharing Bishop Moore's last message. Oscar Moore was a beloved minister and bishop of the International Pentecostal Holiness Church. With roots in Hammon, OK Bishop Moore rose to leadership in the IPHC and touched the world with his life well lived."
