What does the Bible say about the importance of hearing the gospel?

According to Romans 10:17, faith comes by hearing and hearing by the Word of God. However, natural hearing does not guarantee faith or understanding. The Apostle Paul emphasizes that it is the divine power of the Holy Spirit that enables sinners to truly hear and believe the gospel. Many hear the message audibly but do not comprehend it spiritually. This distinction reminds us that salvation is rooted in God's sovereign grace, not merely in human ability to comprehend or respond to the gospel message.
