2 Corinthians 1:18-20

But [as surely as] God is faithful and means what He says, our message to you is not “Yes” and “No” [at the same time]. For the Son of God, Jesus Christ, who was preached among you by us, by me, Silvanus, and Timothy, was not “Yes” and “No,” but has proved to be “Yes” in Him [true and faithful, the divine “Yes” affirming God’s promises]. For as many as are the promises of God, in Christ they are [all answered] “Yes.” So through Him we say our “Amen” to the glory of God.
