2 Corinthians 10:1-2

And now a personal but most urgent matter; I write in the gentle but firm spirit of Christ. I hear that I’m being painted as cringing and wishy-washy when I’m with you, but harsh and demanding when at a safe distance writing letters. Please don’t force me to take a hard line when I’m present with you. Don’t think that I’ll hesitate a single minute to stand up to those who say I’m an unprincipled opportunist. Then they’ll have to eat their words.
