Ephesians 6:17 - Coke's Commentary on the Holy Bible

And take the helmet of salvation, &c.— "Possess that cheerful hope of complete deliverance and eternal happiness, which will cover your head in the day of battle, and give you a well grounded boldness and confidence, which will greatly conduce to your success: and brandish in your hand the sword of the Spirit, which is the word of God, those declarations of his word and gospel which his Spirit has inspired, and by a firm confidence in which you will be able, not only to defend yourselves, but to repel your adversaries."
