After the crucifixion the disciples hid away frightened to death of what the authorities might do to them. When Christ appeared to them after the resurrection they were much encouraged but they were still in no position to serve God. It was therefore necessary for them to be empowered by the Holy Spirit. The Lord told them not to leave Jerusalem for it was there that they would receive power when "the Holy Spirit is come upon you". Then on the day of Pentecost they were filled with the Holy Spirit and transformed from frightened men, into men willing to minister to others in His name, inspired and emboldened by the Holy Spirit. Just as Peter was unable to preach as he did on the day of Pentecost without the Hoy Spirit, so Christians today are unable to preach and teach in power or live according to the demanding rules of Christ unless they are similarly filled and empowered. This book explains in simple terms the sovereignty of God, the spiritual nature of life with God, and man's need of God along with the danger of attack by the evil one, the importance of sacrifice, what hell is and how spiritual power from on high can be received. It is essential reading for those wanting to more fully understand the deeper things of God and be a better servant and disciple of Christ.About the Author: After an electrical engineering apprenticeship in the Royal Navy, Peter went on to serve on a number of ships in different parts of the world, finally being responsible for the weapons maintenance department of a frigate and lecturing to trainee officers on weapon systems.
