Worrying is carrying tomorrow’s load with today’s strength — carrying two days at once. It is moving into tomorrow ahead of time. Worrying does not empty tomorrow of its sorrow; it empties today of its strength.
Corrie ten Boom (1892-1983) Dutch evangelist, concentration camp survivor
He Cares, He Comforts (1977)

See Spurgeon.
I found this quote in ten Boom’s /Jesus is Victor/ (1985). Google Books only has snippet views, but these two comprise the full quote: http://bit.ly/2qTi9mi, http://bit.ly/2rNmck8. I also found the last sentence in /Clippings from My Notebook/ (1982): http://bit.ly/2qdDWnE.
Ah, thank you. Digging a bit further, I found an even earlier reference, as noted. The other books appear to be more “best of” collections of earlier pieces.
