According to Pieter Potgieter, the New Testament teaches that, 'The course of history between the resurrection and the second coming of Christ is a course of inevitable victory for his kingdom. In this process the Holy Spirit is fully involved. The outpouring of the Spirit on the day of Pentecost is nothing less than the indisputable sign of this very victory in the world.' Tracing the theme of the work of the Spirit through the book of Revelation, this booklet contains a series of ten beautiful and encouraging meditations on the ministry of the Spirit. Christians in many different places and circumstances will find it to be a source of profound blessing and instruction.
