Constant Prayer, Ephesians 6:18-20

With all prayer and supplication, pray at every opportunity in the Spirit. To that end, be watchful with all perseverance and supplication, for all the holy ones 19 and also for me, that speech may be given me to open my mouth, to make known with boldness the mystery of the gospel 20 for which I am an ambassador in chains, so that I may have the courage to speak as I must.

Speech is when it is necessary, when it may seem difficult at times. Our voice needs to be persistent during prayer, especially for all who are holy. At some point be ready to be bold and have the courage to speak the gospel. We must defend what is good and righteous for the sake of humanity.
