In The Armor of God Bible Study by Priscilla Shirer, you learn in the first week that there is a spiritual reality behind the physical one that we see, and that there is a war going on whether or not we engage in it. We need our spiritual eyes opened!
In addition to putting on the armor of God (as described in Ephesians 6:10-18) we need to remember to pray. Everything that Priscilla Shirer talks about in the first week of the study (entitled “Sizing up the Enemy”) is illustrated here, so take a look! Download the PDF here.
