Ephesians 6:17-19

And take the helmet of salvation, and the sword of the Spirit, which is the word of God: praying always with all prayer and supplication in the Spirit, and watching thereunto with all perseverance and supplication for all saints; and for me, that utterance may be given unto me, that I may open my mouth boldly, to make known the mystery of the gospel
