The ethical objective of the Christian as presented by the author of Ephesians is to develop a pattern of life, which is appropriate to one who has become a child of God (5:2).  This involves laying aside the old self and putting on the new (4:17-24) and walking no longer in the darkness under the control of the enemy (2:6-14; cf. 2:2), but walking in the light. (Arnold, 1989)
