II Corinthians 1:17-22

Therefore, when I was planning this, did I do it lightly? Or the things I plan, do I plan according to the flesh, that with me there should be Yes, Yes, and No, No? But as God is faithful, our word to you was not Yes and No. 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 in Him was Yes. For all the promises of God in Him are Yes, and in Him Amen, to the glory of God through us. Now He who establishes us with you in Christ and has anointed us is God, who also has sealed us and given us the Spirit in our hearts as a guarantee.
