This is taken from Everyday Prayers: 365 Days to a Gospel-Centered Faith, by Scotty Smith:
"Praying the gospel involves engaging with all three offices of Christ: Jesus as prophet, priest, and king. Engaging him as our prophet, we listen to Jesus and we look for him in every part of the Scriptures (Luke 24:27). Engaging him as our priest, we honor Jesus as the perfect sacrifice for our sins, the righteousness we have by faith, and our loving Savior and High Priest who meets and greets us at the throne of his grace. Engaging him as our king, we submit to Jesus as the one who is making all things new—including us and the broken world all around us."
