It is sad that this happens. I know pastors have it hard a lot of times because they have a church with people on all different spiritual levels. Some know hardly anything about the Bible while others are very well versed. I've had people come to me and say that they are not getting fed in church. My reply usually is, "How hungry are you?" Because when you are really hungry, anything sounds really good.
I love listening to preaching and according to the Bible His Word will not return void. As long as the Word of God is getting preached and I'm letting God work in me, I will get something out of that message, no matter if a kid is preaching or a seasoned preacher.
