The witness of Jesus Christ and his disciples was accompanied by mighty words and mighty works. Drawing on the Gospel of Luke and the Acts of the Apostles, Dr. David N. Gambo demonstrates that this power came from the anointing of the Holy Spirit, without which neither Jesus nor his disciples would have been able to fulfil their ministry. Gambo utilizes an exegetical analysis to develop a theology of Spirit-empowered preaching – preaching characterized by Spirit-words and Spirit-works. If ministers of the gospel are to model their ministries on Jesus of Nazareth, into whose image humanity seeks to be transformed, then the role of the Holy Spirit cannot be ignored. Gambo issues a powerful challenge to those interested in homiletics and pneumatology, as well as to all who preach and minister in the name of Jesus Christ.
