Why is preaching the Gospel important according to the Bible?

In Matthew 10:7, Jesus instructs His disciples to preach that the kingdom of heaven is at hand. This primacy of preaching reflects its critical role in the Christian faith, as seen also in Romans 10:17, which states that faith comes by hearing and hearing by the Word of God. Preaching not only conveys the message of salvation but also invites individuals to respond in faith. It is through the proclamation of the truth that the Holy Spirit works to change hearts and lives. Furthermore, the Great Commission (Matthew 28:19-20) emphasizes the command to go and make disciples, whereby preaching acts as the means through which the lost are sought and brought into the fold of Christ.
