Paul is talking about the spiritual armour found in Ephesians 6.
I am getting contact from pastors concerning their flocks. They are in fear and great anxiety. There are many seeing pillars of their lives disappear. I would like to encourage you all to write to me, even if you are fearful and even if fear has got you. The armour is what comes from the Word and the Spirit.
