You have never tried to make your message irrelevant, boring, or incomprehensible.
At least I hope not!
But you find yourself preaching while questioning your effectiveness. You walk up to deliver a sermon lacking confident in your content. You question your ability. Your capacity. Even your calling. You feel your church more tolerates the message than engages in the content.
Of course, this isn’t the case EVERY time you preach, but more times than you’d like to admit.
The easy solution is to become hyper-spiritual. Say you are “trusting” God and the Holy Spirit to speak in spite of you. Not to be irreverent, though. We know at the heart of preaching, spiritual intervention is necessary. But we all know the difference between “I’m ready to go and trusting God to do what only he can do,” and “I’m not close to ready, so God perform a miracle.”
