Can the sermon bless the preacher more than the hearers?
Perhaps this can happen. And perhaps this happened on Wednesday of this week at our mid-week service at church. I preached on Psalm 6 and I had a wonderful time. I'm not sure if things came out cohesively and cogently but in my heart and soul, I was greatly edified by God's Word.
I don't think I'm overstating the fact that this may have been--for me personally--one of the most edifying sermons I've ever preached.
If you so choose, you can listen to it here.
Isaiah 55:11 So shall My word be which goes forth from My mouth; It shall not return to Me empty, Without accomplishing what I desire, And without succeeding in the matter for which I sent it.
