For a lesson on the armor of God, get Bible Alminacs, and pictures with descriptions of war weapons and protection used in the era when Ephesians was written.
Have enough materials on hand for your group to split up and research one of each of the types of spiritual armor, and connect it historically with themselves spiritually. Begin by reading from the Bible Eph 6 :10-18, and breifly discuss.(WHEN the evil happens, not IF..etc. The idea is to help this concept to be less abstract, and for students to make important corrolations for themselves. I had at least one resource for each group, then they traded off. It would have been even better if I had slides and even more background information, but the students came up with spiritual connections which were great. After plenty of time for groups to do their fact finding, they presented each piece of spiritual armor to the group, and got feedback. Reread the passage from Ephesians, and discuss. Close with prayer asking for each person in the room to remember their armor, and why.
Some things students put together were that the shield of faith- when shields were researched, they used to be soaked in water to extinguish flaming arrows. Jesus is referred to Living Water – soak ourselves in THAT! Keeping our feet fitted with the gospel of peace- when we are on slippery surfaces, if we don’t have the right footwear on, we slip. If we stay in God’s Word, we keep ourselves spiritually stable, the stumbles are less frequent,and when we are in a forward relationship with God, we cannot be growing further and sliding spiritually….the helmet of Salvation – helmets keep our brains in if we receive a blow to the head, or have an accident – just as if we receive spiritual blows, with salvation, we know we won’t lose it- it’s a guarantee. A good swordsman never leaves his sword- he’s always ready! So should we always be ready to share Christ with others, and be ready to stand up for him. The sword is also the only weapon- everything else is defense…hmmm- makes ya think! The breastplate- with it we never need to turn our backs- with God on our side , we can face anything, because he will not turn form us. This is just some of what students came up with- good stuff with visuals, research, and discussion. This activity took about one hour.
