Andrew Murray's writings were a cherished and vital part of his ministry in Africa. In this classic work, Murray stressed the importance of one truth: that the Holy Spirit must be known by every believer as an indwelling life of spiritual power. For Murray, this indwelling was to be accepted and treasured, until it became part of the consciousness of the believer: As the Holy Spirit possesses us, all of our lives, even the least things, must be surrendered to His leading. If God's people can learn to wait on the Holy Spirit for divine leading and working, placing ourselves entirely at His disposal; then there will be manifestations of the Spirit's power in the church such as the world has never known. In this book, Murray teaches on all aspects of the Holy Spirit, in the hope that God's glory would begin to work through His church in powerful ways that would be a witness for all the world.

"In my observation of the lives of believers, I have been very deeply impressed with one thought: that our prayer for the mighty working of the Holy Spirit through us and around us can only be powerfully answered as His indwelling in every believer is more clearly acknowledged and lived out." —Andrew Murray
