Psalm 39:4
Lord, let me know my end,
and what is the measure of my days;
let me know how fleeting my life is.

Creator God,
You are from everlasting to everlasting
    and my days are but one hand-breath in your sight.
Make me mindful of my mortality,
    so I will not take for granted one day.
In the name of the One who blesses all with life,
                                        Amen.
