C. S. Lewis
in Letters to Malcolm
(partially quoted in Jan Karon's
A New Song, page 254)
And this would be the explanation for something I find in my own life. Once I say "we beseech Thee to hear us, good Lord" while the rest are praying "we implore you to hear us, good Lord," ...
or I say "conceived by the Holy Ghost" when y'all say "conceived by the Holy Spirit," ...
or I sing "go before the face of the Lord to prepare His way" while the others sing "go before the Lord to prepare His way," ...
that clash in wording
(or even focusing on the words
so that I am able to say what y'all say)
means I stop praying
and "think about praying."
