A prayer that I read on a blog today that I feel could apply to committing ourselves to prompt action for good and progress.

Largire nobis, quaesumus, Domine,
semper spiritum cogitandi quae recta sunt,
prompitus et agendi,
ut, qui sine te esse non possumus,
secundum te vivere valeamus.

Translates to:

We beg you, O Lord, bestow upon us
the spirit of thinking always things which are correct,
and of carrying them out promptly,
so that we who are not able to exist without You
may be able to live according to Your will.
