2 Corinthians 1:17-19

17 Do you think that I made these plans without really thinking? Or maybe you think I make plans as the world does, so that I say “Yes, yes,” and at the same time “No, no.”

18 But since you can believe God, then you can believe that what we tell you is never both “Yes” and “No.”

19 The Son of God, Jesus Christ, that Silas and Timothy and I preached to you, was not “Yes” and “No.” In Christ it has always been “Yes.”
