Why is it that when I read of great men of the past, I cannot simply thank God for them and seek to follow their example? Why does jealousy flame within me and why is ambition stirred?
I do want to do great things for God… and I’m becoming more and more convinced that this desire may suffice to keep me from it. Would God use such a proud vessel?

I know a very helpful book you should read about this.
It’s called Preaching and Preachers by Martyn Lloyd-Jones.

Have you got a copy I could borrow?
EDIT: never mind, Fisher library does.
I have no doubt that God could use ‘such a vessel’, as you put it – He approached Paul when he was still Saul, didn’t He? God doesn’t wait until perfection is reached to use someone (thank goodness, otherwise I don’t think we could ever do anything!)
You might also want to check out “Holy Discontent” by Bill Hybels – I haven’t read it yet myself but I’ve heard it’s a good book on this topic
Thanks for your encouragement. I still struggle to believe that he would want to use me…
I suppose all I can do is work as for the Lord in whatever capacity He has given me, and wait to see what He does with it.
