How do we know that God gives boldness to preachers?

According to Ephesians 6:19, the ability to preach boldly is not an inherent trait but a gift from God. This indicates that true boldness in preaching comes from divine empowerment. Paul asked for prayer that he might speak boldly, acknowledging that without God's intervention, a preacher cannot effectively declare the gospel. The need for prayer among congregants highlights the dependency of the ministry on God's grace and the recognition that boldness aligns with God's purpose and will in evangelizing the lost.
