What does the Bible say about the role of boldness in preaching?

Boldness in preaching is a crucial theme in the New Testament, particularly seen in the lives of the apostles, including Paul. Acts 4:13 notes that when the religious leaders saw Peter and John’s boldness, they recognized that these uneducated men had been with Jesus. This indicates that true boldness arises from a genuine relationship with Christ. When one has seen and heard the voice of the Lord, it empowers them to speak with conviction and courage, irrespective of the opposition. This boldness is not natural but a result of a profound understanding of God's sovereignty and grace, compelling believers to share the gospel fearlessly.
