Who said that ???
Sadly your reply indicates you have not understood my position.
Being under financial obligation to deliver a Spiritual Service is the problem.
I have first hand knowledge of the stress one can come under to deliver a sermon when the personal communion with Him is lost.
This leads to dishing up second hand 'inspiration' which God hates.
Maybe you meant something else?
I've preached/teached through thick and thin, with and without a "feeling" of being prepared. As far as the stress level goes, it's a matter of faith, as I see it.
I had a memorable lesson in that one time when I was going to be teaching concerning relying on the power of the Holy Spirit in ministry. No amount of study and prayer was yielding the lesson I wanted to present. I had nothing! At one point I had to laugh, I realized God was making me rely completely on His Spirit, no advance helps!
Evening service was starting in half an hour, and there was just time for the pre-service prayer meeting. No one else was joining me that day. And that was when I felt God was ready, so I picked up a pen, and it all flowed out, notes for my message, the points to make, the Scripture references, all of it!
I'm not sure what you mean by "second hand inspiration", I think you mean fishing around through old sermon notes looking for something to use? I don't even see a problem with that, I've seen God use that to produce the message I believe He wanted. I've learned that God leads in all sorts of ways, and we are to follow the bouncing ball.
Whether we are in a paid or unpaid ministry position our heart should be the same, trusting God for the fruit of our labors, and trusting God to provide for our needs. Each in it's own place.
For me, it's not about, I have to get up there and preach so I can get my paycheck, it's a matter of, I'm preaching according to God's plan for me to serve others, I'll do the best I can regardless of how I feel or what's going on with me, because I serve the Living God.
It's all about faith and obedience.
I've had times where I've taught Bible study after having a horrible fleshy-mind day, coming with a guilty mind, shamed heart, knowing how far off track I've been, then to see the Holy Spirit start pouring words out of my mouth, because it's His ministry not mine, and if I'm not up to snuff, He is, and is perfectly capable of working out His will.
Being a Bible teacher is first about teaching me.
Much love!
