Think not, when the wailing winds of autumn
Drive the shivering leaflets from the tree,—
Think not all is over: spring returneth,
Buds and leaves and blossoms thou shalt see.
Think not, when the earth lies cold and sealed,
And the weary birds above her mourn,—
Think not all is over: God still liveth,
Songs and sunshine shall again return.
Think not, when thy heart is waste and dreary,
When thy cherished hopes lie chill and sere,—
Think not all is over: God still loveth,
He will wipe away thy every tear.
Weeping for a night alone endureth,
God at last shall bring a morning hour;
In the frozen buds of every winter
Sleep the blossoms of a future flower.
