"To sum up all things in Christ" is the mystery of God's will. This needs to be first realized in the church as well as in each individual member before it can be fulfilled in the universe. How very urgent it is for believers to know the reality of Christ as being our all and in all. For God has not given us many things; He gives us only Christ. Things are dead, but Christ is living. Christ must be all things to us. In this small volume, brother Watchman Nee illustrates this basic principle of "not things but Christ" from various angles with many practical helps. His heart burden is for Christ to become real to us. Let things pass away, let life fill us. May Christ be all and in all.
