Grace If You Do and Grace If You Don't?

Lord, it belongs not to my care
Whether I die or live;
To love and serve Thee is my share,
And this Thy grace must give.

If life be long, I will be glad,
That I may long obey;
If short- then why should I be sad
To soar to endless days?
-Richard Baxter
(quoted from Knowing God by J.I. Packer, 31-32)
