If you want to know the essence of biblical theology or the centrality of salvation according to the Scriptures, it’s really not that complicated. You don’t need to research volume after volume after volume of some esoteric, wig-head, dry-as-dust theologian. You don’t even have to go to seminary to learn it. In fact, even a worthless and pathetic good-for-nothing country bumpkin pastor named Brent Kuhlman can teach it to you today.
