From Colossians 4

O God, our Master in heaven, make us fair and just in our dealings with others; keep us persistent in prayer for them, alert to their needs, and constantly thankful; open doors for us to proclaim the message about the secret of Christ; help us to speak as we should, to make it clear. Keep us wise in the way we act towards those who do not believe, help us always to make good use of every opportunity we have; let our conversation be attractive and inspiring, and teach us how to give the right answer to everyone, through Jesus Christ our Lord. Amen.
