Ephesians 6:18–20

18 Pray at all times in the Spirit, with all prayer and supplication. To that end keep alert with all perseverance, making supplication for all the saints, 19 and also for me, that utterance may be given me in opening my mouth boldly to proclaim the mystery of the gospel, 20 for which I am an ambassador in chains; that I may declare it boldly, as I ought to speak.
