HT Angela for this one which moves us from the (rightly) truncated form used by George VI at the start of war to a version more fitting for life as we experience it now (copyright unknown, formatting as per web so may be inaccurate)...
God Knows
I said to the man who stood at the Gate of the Year,
"Give me a light that I may tread safely into the unknown."
And he replied, "Go out into the darkness, and put your hand into the hand of God.
That shall be to you better than light, and safer than a known way."
So I went forth,
And finding the hand of God,
Trod gladly into the night.
He led me towards the hills
And the breaking of day in the lone east.
So heart be still!
What need our human life to know
If God hath comprehension?
In all the dizzy strife of things,
Both high and low,
God hideth his intention.
God knows. His will
Is best. The stretch of years
Which wind ahead, so dim
To our imperfect vision,
Are clear to God. Our fears
Are premature. In Him
All time hath full provision.
Then rest; until
God moves to lift the veil
From our impatient eyes,
When, as the sweeter features
Of life's stern face we hail,
Fair beyond all surmise,
God's thought around His creatures
Our minds shall fill.
