2 Corinthians 10:9-11

New International Version - UK

⁹ I do not want to seem to be trying to frighten you with my letters. ¹⁰ For some say, ‘His letters are weighty and forceful, but in person he is unimpressive and his speaking amounts to nothing.’ ¹¹ Such people should realise that what we are in our letters when we are absent, we will be in our actions when we are present.
