2 Corinthians 1:17-20

17Was I fickle when I intended to do this? Or do I make my plans in a worldly manner so that in the same breath I say both “Yes, yes” and “No, no”? 18But as surely as God is faithful, our message to you is not “Yes” and “No.” 19For the Son of God, Jesus Christ, who was preached among you by us—by me and Silas and Timothy—was not “Yes” and “No,” but in him it has always been “Yes.” 20For no matter how many promises God has made, they are “Yes” in Christ. And so through him the “Amen” is spoken by us to the glory of God.
