Why is hearing the gospel important?

Hearing the gospel is crucial because faith comes by hearing, and hearing comes through the word of God (Romans 10:17). Paul emphasizes that one cannot believe in someone they have not heard of, and thus preachers are sent to declare the message of the gospel. This is a divine ordinance by God to ensure that His message reaches the hearts of His people. However, despite hearing, not all who listen will respond in faith, as shown in Romans 10:16, indicating that God's work in the heart is also essential for true belief.
