I heard this partially quoted in a Dallas Theological Seminary Chapel podcast (in a message preached by Brent Burckart on 10-18-16) so I looked it up to get the full text. For those may not be in the midst of studying explorers with their kids like I am, or who may not remember him from world history, Sir Francis Drake was the first to circumnavigate the world, between 1577-1580. What a powerful prayer.
The Prayer of Sir Francis Drake
"Disturb us, Lord, when we are too well pleased with ourselves,
When our dreams have come true because we have dreamed too little,
When we arrived safely because we sailed too close to the shore.
Disturb us, Lord, when with the abundance of things we possess
We have lost our thirst for the waters of life;
Having fallen in love with life, we have ceased to dream of eternity
And in our efforts to build a new earth, we have allowed our vision Of the new Heaven to dim.
Disturb us, Lord, to dare more boldly, to venture on wider seas
Where storms will show your mastery;
Where losing sight of land, we shall find the stars.
We ask You to push back the horizons of our hopes;
And to push into the future in strength, courage, hope, and love."
Disturb us, Lord.
