John Gill emphasizes the significance of public hearing of the Word as a vital ordinance in the Christian faith, tracing its roots from the synagogue worship to the early church. He highlights the necessity of attentive and reverent listening, distinguishing between different types of hearers and their responses to the Word. Gill encourages believers to approach the hearing of the Word with prayer, eagerness, and a heart prepared to receive the truth, as it is through hearing that faith is cultivated. He also discusses the benefits of hearing the Word, including conviction, conversion, and spiritual nourishment, urging the congregation to be doers of the Word and not merely hearers.
