This is a prayer that I read that has had a big impact on me lately.

A Prayer by Francis Drake

Disturb us Lord,
when we are too well pleased with ourselves;
when our dreams have come true because we dreamed too little
when we arrive 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 water 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 us into the future in strength, courage, hope and love.
