This present volume is a compilation of messages given by God's servant Watchman Nee at various times and places. They all relate to the communion of the Holy Spirit. The first part consists of two messages on Resurrection, the Holy Spirit, and the Church. A proper perspective on the marvelous work of the Holy Spirit is therein given. The second part, entitled The Outpouring of the Holy Spirit, is composed of six messages on the Outpouring, one message on the Holy Spirit, and the Law, and two messages on the Anointing Oil. And the third part presents four messages on Spiritual Judgment, which is the fruit of the discipline of the Holy Spirit. Such discipline gives spiritual discernment for service.
