The Helmet of Salvation: Ephesians 6:16

Purpose: Paul wrote this section, recognizing both the reality of the constant conflict with spiritual wickedness in high places, and the means by which God strengthens Christians in the battle so they can be victorious.
Proposition: God wants us to focus our thinking on the reality of our coming salvation when we are most prone to discouragement in the battle.
Interrogative: How can we do this?
