I would rather learn from someone who's big enough to admit they have had personal struggles which the Lord has helped them overcome than from someone who acts as though they've been pure they're whole life--God has said in our weakness is when He can be our strength. I remember once, when I returned to college with two small children, and was feeling frustrated with 4 classes to boot, I told God, I can't do this.....He said, I've been waiting for you to ask Me to help you, I never intended for you to do this alone. When we can admit we need His help, He does so much better in our lives.
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)
