In this excellent work on spiritual warfare, Ambrose handles three doctrines: 1) All God's people must be warriors. 2) We have powerful and malicious enemies to contend with. 3) We must wrestle and strive against these enemies. Ambrose shows how Satan attacks the Christian at different times and under different conditions in our lives, and how we can be ready to withstand his assaults. Based on Ephesians 6:12, Ambrose addresses how a Christian is to do spiritual battle against sin, Satan, the world, and the flesh. This work is particularly useful in that he highlights the unique temptations of the various stages of a person's life.
