Page 832 of the Book of Common Prayer has the prayer #59 For Quiet Confidence.

O God of peace, who hast taught us that in returning and
rest we shall be saved, in quietness and confidence shall be
our strength: By the might of thy Spirit lift us, we pray thee,
to thy presence, where we may be still and know that thou
art God; through Jesus Christ our Lord. Amen.

When we visited the National Cathedral I was delighted to find a small plaque on the wall with this very prayer on it. The photo of that plaque hung on my wall for many years.

Many, many years ago I chose Isaiah 30:15 as my ‘life verse.’ It reads:

For thus said the Lord God, the Holy One of Israel:
In returning and rest you shall be saved;
    in quietness and in trust shall be your strength.
But you refused NRSVUE

I have returned to the prayer and verse countless times over the years. I am always stung by the last phrase, “But you refused” or “But you would not.” Oh Lord deliver me from being one who refuses.

There truly is strength in practicing this verse in your daily life. Here are a few ways. Returning and rest, quietness and trust. That hushes my speculations. Calms my rushing about. (maiden name was Rush!) There are so many applications. Try pondering this prayer and verse for 7 days. See what impact it has upon you! I often print things like this and carry them in my pocket throughout the day.

By the might of Your Spirit, LIFT US WE PRAY, to Your Presence where we maybe still and KNOW that you are God.
