What does Acts 4 teach about the relationship between authority and preaching the gospel?

Acts 4 powerfully illustrates the relationship between authority and the preaching of the gospel. When Peter and John were questioned by the Sanhedrin about their healing of a paralyzed man, Peter, filled with the Holy Spirit, boldly declared that the miracle was done in the name of Jesus Christ of Nazareth (Acts 4:10). This account shows that authentic authority for preaching is derived from the Holy Spirit’s empowerment and the recognition of Jesus’ divine authority.

The Sanhedrin was authoritative in religious matters, yet they lacked the authenticity and power that came from being filled with the Spirit. This contrast serves as a reminder for Christians today that true authority does not rest in human institutions or qualifications, but in the Holy Spirit equipping believers to declare the gospel. As stated in Acts 4:12, there is no other name under heaven by which we must be saved, emphasizing the significance of proclaiming Christ's authority in all evangelistic efforts.
