Why is preaching the name of Jesus important for Christians?

For Christians, the preaching of the name of Jesus is fundamental to the faith because it declares the very heart of the Gospel message. Acts 5:42 demonstrates this as the apostles 'ceased not to teach and preach Jesus Christ,' showing their commitment to the command given by God to share the Gospel boldly. The name of Jesus signifies His authority and work of redemption, making it the focal point of Christian preaching. Without declaring His name and the significance of His sacrifice, the church loses its identity as the pillar and ground of truth outlined in 1 Timothy 3:15. The importance of this is further emphasized by the fact that through preaching Jesus, individuals are called to repentance and faith, receiving the transformative grace necessary for salvation.
