This book calls all genuine disciples of our Lord Jesus Christ, both vocational ministers and lay people, to serve our Savior by carrying out His marching orders His way. This demands that the doctrines of man, sin, salvation, the Word, and the Spirit have full sway in all that we do in the name of Christ. Whatever we are engaged in, whether witnessing to the lost or carrying out our various other responsibilities (e.g., preaching, teaching, counselling, and encouraging), we must be divinely directed by the practical implications of God's grace. Then we, as faithful channels, may joyously come to understand that it is God who causes any and all growth (1 Corinthians 3:6).
