Sometimes I wonder how much of my efforts have been a waste.

This morning, I take fresh courage in Psalm 90:

Lord, thou hast been our dwelling place
in all generations.

For a thousand years in thy sight
are but as yesterday
when it is past,
and as a watch in the night.

In the morning
it flourisheth,
and groweth up;
in the evening
it is cut down,
and withereth.

So teach us to number our days,
that we may apply
our hearts
unto wisdom.

O satisfy us early with thy mercy;
that we may rejoice
and be glad
all our days.

Make us glad
according to the days
wherein thou hast afflicted us,
and the years
wherein we have seen evil.

Let thy work appear unto thy servants,
and thy glory unto their children.

And let the beauty of the Lord our God
be upon us:
and establish thou
the work of our hands upon us;
yea, the work of our hands
establish thou it.

Yes.

Please.

Amen.

Surely you could add something...
