The Christian life can be described as a spiritual battle and it is much more every day than many have led us to believe. This helps to make sense of so many trials in Christian living. In this chapter, Paul explains the nature of this spiritual warfare. Though the devil stands fearsome, Christ's disciples are more than equipped to stand against him and his schemes. These closing verses of Ephesians pulls together the whole letter to demonstrate how the 'armour' of chapters 1–3 equips us for the 'battle' of chapters 4–6.
