This valuable exposition of the theme of 'spiritual warfare' is in four sections. The first is concerned with the nature of Satan and his activity in the world God has made. The second examines the different dimensions of Christ's victory over Satan. The third considers ways in which Christ's victory over Satan impacts God's people. The final section looks at various areas in which believers must fight sin and Satan. Two concluding chapters examine the weapons with which God equips his people for their spiritual warfare.
