Spiritual power is needed today. This power is needed to be like Christ in character and in deed. It is the power of God - The Father, the Son and the Holy Spirit. The Lord meant that the church as His body, and the believer as a member of His Body, would manifest spiritual power in character and service.
The church is, generally speaking, powerless. The lives of many believers are a tragic contradiction of the gospel they talk about. In the face of diseases, demons, and the like, many believers stand totally powerless. There is a growing confidence in human skills, human techniques, human methods, and human organisations. On the whole, many live and act as if God were absent. This ought not to be so. This must not continue to be so.
In the life of the church and in the life of each believer, there must be power that cannot be accounted for on any grounds. People looking must be able to say, "This is God at work" and nothing else.
The power of the Lord is made available to all who come to Him. His power is manifested in full measure through channels that are fully opened to Him and that give Him the freedom to do His work His way, and in His time.
Although spiritual power can be manifested without holiness and obedience, those who are open to and co-operate with the Lord through prayer, the Word, holiness, a surrendered life, Christian character, the gifts of the Holy Spirit, and so on, will begin to experience spiritual power, and as they continue to seek the Lord and His might, they will grow in the knowledge of Him and His might.
We send out this book with prayer that it should be used by the Lord to stir hunger after the Lord and the power of His might.
