When Paul came to Ephesus, he found some disciples and asked them, Did ye receive the Holy Spirit when ye believed? They replied that they had not heard that there even was a Holy Spirit.
Many Christians are in a similar position today: soundly saved and born again of the Holy Spirit, but not walking in the power of the Spirit.
Andrew Murray says that the biggest lack in the church today and the single solution to all its problems is the real moving of the Spirit. Whilst so much time is wasted with men's ideas and men's methods, if we were simply to seek the power of the Holy Spirit and allow Him to work, the whole Christian landscape would change.
In an age when methodology is on the increase, Andrew Murray takes us back to basic biblical principles, showing us how to experience the Holy Spirit's power, and why it is the one thing needful.
