Passage
Have also the helmet of salvation, and the sword of the Spirit, which is God's word;
Have also the helmet of salvation, and the sword of the Spirit, which is God's word;
Ephesians 6:15 and shod your feet with [the] preparation of the glad tidings of peace:
Ephesians 6:16 besides all [these], having taken the shield of faith with which ye will be able to quench all the inflamed darts of the wicked one.
Ephesians 6:17 Have also the helmet of salvation, and the sword of the Spirit, which is God's word;
Ephesians 6:18 praying at all seasons, with all prayer and supplication in [the] Spirit, and watching unto this very thing with all perseverance and supplication for all the saints;
Ephesians 6:19 and for me in order that utterance may be given to me in [the] opening of my mouth to make known with boldness the mystery of the glad tidings,
The verse centers on "Spirit", "helmet", "salvation", "sword", and "god's". It is saying that the verse draws attention to "Spirit" and "helmet", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 16's "besides all these having taken the shield..." into verse 18's "praying at all seasons with all prayer...", so "Spirit" and "helmet" belong inside that flow. In Ephesians context, the local focus is grace, union with Christ, the church, and new creation.
A plain takeaway is to answer the verse's own emphasis on "Spirit" and "helmet" with trust shaped by these words, not by a vague optimism outside the passage.
