Nee has written a thought-provoking book that will challenge the reader to consider the sufficiency of Christ in all things.Nee emphasizes that Christ is our life, truth, and power. Nee also mentions that the Christian is to let go of all self-sufficiency and instead let Christ be our sufficiency.Another important point Nee mentions is the futility of achieving human unity apart from Calvary - a rebuke to the world's system of doing things.All in all, an excellent read that will challenge your thinking. Read and be encouraged!
