2 Corinthians 1:18-22

But as God is faithful, our word to you is not yes and no. For the Son of God, Christ Jesus, who was preached among you by us—by me and Silvanus and Timothy—was not yes and no, but is yes in Him. For as many as are the promises of God, in Him they are yes; therefore also through Him is our Amen to the glory of God through us. Now He who establishes us with you in Christ and anointed us is God, who also sealed us and gave us the Spirit in our hearts as a pledge.
