C.H. Spurgeon emphasizes the futility of arguing over theological disputes, likening it to two doctors who neglect their meal while a simple farmer enjoys his food. He encourages believers to focus on feasting upon the Word of God rather than getting caught up in endless debates that yield no spiritual nourishment. Spurgeon highlights that while theological questions are important, the essence of faith lies in believing in Jesus Christ, who is the true source of joy and salvation. He advises that instead of being consumed by controversy, one should rest in the Lord and trust in His promises. Ultimately, the sermon calls for a simple, heartfelt faith over intellectual disputes.
