We must not confide in the armor of God, but in the God of this armor, because all our weapons are only mighty through God.
William Gurnall, The Christian in Complete Armor
Gurnall, 1617-1679, was a Puritan preacher in England and author of the classic work The Christian in Complete Armor on Ephesians 6:10-20 that continues to serve as a dense resource (more than 1,200 pages) on this passage of scripture.
