How do we know the importance of preaching the word?

The importance of preaching the word is highlighted in 2 Timothy 4, where Paul instructs Timothy to preach not only for encouragement but to reprove and rebuke. The role of preaching is to expose the truth of the gospel, which confronts the human heart with its own corruption and points it to Jesus Christ, who is the source of redemption. True preaching engages with the spiritual realities of sin and grace, calling believers to repentance toward God and faith in Christ. This guidance is essential for building a sound and sacrificial church that honors God.
