Recollecting those who love to introduce themselves/others to me just so I could 'trust' them: Dr. Stephen Tong is my favorite teacher; I'm a good friend of Rev. Tong; I have been involved in his ministry for 100 years; etc.
My only responses are: So what?; Good for you!
I don't care if it's Rev. Tong's grandfather, all I care is: If you're here to serve God or not?
