I posted this a year or two ago, but it's worth re-posting.

O merciful God, be Thou unto me
A strong Tower of defence,
I humbly entreat Thee.
Give me grace to await Thy leisure,
And patiently to bear
What Thou doest unto me;
Nothing doubting or mistrusting
Thy goodness towards me;
For Thou knowest what is good for me
Better than I do.
Therefore do with me in all things
What Thou wilt;
Only arm me, I beseech Thee,
With Thine armor,
That I may stand fast;
Above all things taking to me
The shield of faith;
Praying always that I may
Refer myself wholly to Thy will,
Abiding Thy pleasure, and comforting myself
In those troubles which it shall please Thee
To send me, seeing such troubles are
Profitable for me; and I am
Assuredly persuaded that all Thou doest
Cannot be but well; and unto Thee
Be all honor and glory. Amen.

~ The prayer of seventeen-year-old Lady Jane Grey, in her prison cell before she was beheaded in 1554

I love this poem so much that I re-read it often to remind myself of its truth and beauty.  It comforts me to think that this prayer is as applicable and full of God's providence to me, in the relatively small trials of my life, as it was to Lady Jane Grey as she contemplated her premature death at the hands of an evil monarch.  What faith and trust she had in God's will!
