1D Ephesians 4:15 says that we grow up into the Head; the word Head here indicates that our growth in life by the increase of Christ should be the growth of the members in the Body under the Head.
11d We need to be permeated and saturated with Christ and to have Christ wrought into our being; then, in reality and practicality, Christ will be every member, every part, of the one new man—3:10-11.
