This book is a fresh and lively study of the Epistle of Paul to the Ephesians that presents us with some basic facets of our faith, by examining the three themes of this epistle: spiritual status, conduct, and the spiritual battle the believer faces. If the believer wants to be a useful instrument in God's hands, he should be in good shape in his spiritual purity, in his daily life, and in his fight against the forces of evil. All this and more is explained simply and biblically, drawing especially on experiences in China's past.
