I went through nursing school in the same position. I was scared to death that I'd never make it... since I passed High School, by the skin of my teeth. God called me into nursing.. so I put it in His hands, prayed over every test..and graduated with scholastic honors. (Now THAT...is a MIRACLE!!) *chuckle*
I didn't have time in those days to eat and sleep... much less be involved in church activities... so I depended quite heavily on those old heretic evangelists to keep me going through the rough times. (/sarcasm)
Many souls are in heaven because of TBN and those that make fun and critize it will have to answer for it one day!
