Nice poem / hymn for a hard day

I was at the Saddleback Women's study this evening, and really liked this poem / hymn Chaundel read to the group. Not sure when or who wrote it, but maybe it will brighten your day, too :)

God hath not promised skies always blue,
Flower-strewn pathways all our lives through;
God hath not promised sun without rain,
Joy without sorrow, peace without pain.

But God hath promised strength for the day,
Rest for the labor, light for the way,
Grace for the trials, help from above,
Unfailing sympathy, undying love.

God hath not promised we shall not know
Toil and temptation, trouble and woe;
He hath not told us we shall not bear
Many a burden, many a care.

But God hath promised strength for the day,
Rest for the labor, light for the way,
Grace for the trials, help from above,
Unfailing sympathy, undying love.

God hath not promised smooth roads and wide,
Swift, easy travel, needing no guide;
Never a mountain, rocky and steep,
Never a river, turbid and deep.

But God hath promised strength for the day,
Rest for the labor, light for the way,
Grace for the trials, help from above,
Unfailing sympathy, undying love.
