Why is preaching the gospel of Jesus Christ important for Christians?

Preaching the gospel is central to the Christian faith because it embodies the message of salvation through Jesus Christ. In Luke 10:8-9, Jesus instructs His followers to proclaim the presence of the kingdom of God and to heal the sick, showing that the message of the gospel is one of restoration and hope. It is through this preaching that the urgency of responding to God's grace is communicated, and it serves as the means by which God draws sinners to Himself. As Romans 10:14-15 notes, how can they hear without a preacher? The proclamation of Christ, therefore, is vital not only for the edification of believers but also for the salvation of the lost, as it is the basic means through which the Holy Spirit works in the hearts of people.
