Peter Adam writes about the ongoing process of growth that being a preacher requires:
Being a preacher requires ever-increasing Biblical intelligence, emotional intelligence, theological intelligence, and pastoral intelligence. Of course, by intelligence i mean alert and perceptive wisdom. I don’t mean cleverness but depth of understanding and wisdom.
We need to be Biblically, emotionally, theologically, and pastorally wise to understand the Bible, to understand people, and to serve people in our sermons.
