Analysis of Trust

I am thy grass, O Lord!
I grow up sweet and tall
But for a day; beneath Thy sword
To lie at evenfall.

Yet have I not enough
In that brief day of mine?
The wind, the bees, the wholesome stuff
The sun pours out like wine.

Behold, this is my crown;
Love will not let me be;
Love holds me here; Love cuts me down;
And it is well with me.

Lord, Love, keep it but so;
Thy purpose is full plain;
I die that after I may grow
As tall, as sweet again.
