The soul craves rest.
Our wills sometimes rejoice in striving;
our bodies were made to (at least sometimes) know the exhilaration of tremendous challenge;
our minds get stretched when they must focus even when tired.
But the soul craves rest.
The soul knows only borrowed strength.
The soul was made to rest in God the way a tree rests in soil.
From the chapter, “The Soul Needs Rest” in Soul Keeping, John Ortberg
