“The mark of solitude is silence, as speech is the mark of community. Silence and speech have the same inner correspondence and difference as do solitude and community. One does not exist without the other. Right speech comes out of silence, and right silence comes out of speech.
“Silence is nothing else but waiting for God’s Word and coming from God’s Word with a blessing. But this stillness before God’s Word will exert its influence upon the whole day. If we have learned to be silent before the Word, we shall also learn to manage our silence and our speech during the day.”
