Yeah, that's not his son... lol. He has two (beautiful) little girls, but no biological sons. He does, however, have several "sons" in ministry, and they are all as phenomenal as he is.
I'm not really into watching clips, but if you like Nathan Simmons, you should do a search in YouTube for Supt. Tim Cox (who is the new Supt for Supt. Simmons' district) or Steven Hill (the Youth Pastor at Nathan Simmons' church).
Another "son" is Pastor Mark House (but I'm not sure if he's on YouTube).
They really all preach JUST like him, but not as soft-spoken as he is before he gets all tuned up. LOL
His wife is also a good preacher. Lady Angelic Simmons is a "daughter" of Susie Owens... she is a lot like her "mama."
