Today's reading is a favorite image for many Christians, and quite unfamiliar for others. Paul talks about prayer and the Christian life more generally in terms of putting on the armor of God. The idea is that our life of faith can be a struggle. We're always surrounded by temptation to do what is easy instead of what is faithful. Sin, selfishness and the devil himself try to knock us off our path. In all our challenges we reach out to God for help, and we strengthen ourselves with God's word and with spiritual preparation. Notice how much attention Paul gives to prayer and how he asks the church to support him in prayer so he can speak boldly. We are all in it together.
