This is not something I wrote, but something I was given on my original Via de Cristo retreat weekend and kept. It seems appropriate for our theme of “spending time.” The author is unknown:
There are two days in the week upon which and about which I never worry–two carefree days kept sacredly free from fear and apprehension. One of these days is Yesterday. Yesterday with its cares and frets and pains and aches, all its faults, its mistakes and blunders, has passed forever beyond my recall. It was mine: now it is God’s.
The other day that I do not worry about is Tomorrow. Tomorrow, with all its possible adversities, its burdens, its perils, its large promise and performance, its failures and mistakes, is as far beyond my mastery as its dead sister, Yesterday. Tomorrow is God’s day: it will be mine.
It isn’t the experience of Today that drives us mad. It is the remorse of what happened Yesterday and fear of what Tomorrow might bring. These are God’s Days–Leave them to Him.
