Another favorite quote

In Pres. Boyd K. Packer's last general conference address, he quoted a poem that has been a favorite of mine when he quoted it in another general conference talk YEARS ago.

Here it is:
With thoughtless and impatient hands
I tangle up the plans
The Lord hath wrought.
And when I cry in pain,
He saith,
"Be quiet, child,
While I untie the knot."
