What does the Bible say about the Holy Spirit's assistance in preaching?

The Scriptures teach that the Holy Spirit's assistance is crucial for effective ministry. As expressed in John 15:5, 'Without me you can do nothing,' affirming that we cannot adequately meditate or speak without His influence. This is not to diminish the use of means such as diligent study and prayer; instead, reliance on the Holy Spirit should be paramount, acknowledging that any lack in our preparation can lead to words that darken counsel instead of enlightening. Such dependence allows God to receive all glory for our abilities, while we remain cognizant of our own limitations.
