Regarding Dr. Owuor and not hearing him use the name of Jesus. First off his radio broadcast is entitled JESUS IS LORD. Obviously you haven't done to much research. Let me lead you to a couple (of many) of his revival meetings on You-Tube where he clearly uses Jesus' Name.
1. THE NAKURA REVIVAL MEETING
2. THE KISUMU REVIVAL MEETING
3. THE TORONTO 20 SEPT. 2008 ....... Start with this one, in just seconds you'll hear him say, what you say, you haven't heard.
Hope this proves to be a help to you.
