2 Corinthians 1:18-22

18But as God is faithful, our word toward you is not yea and nay. 19For the Son of God, Jesus Christ, who was preached among you by us, even by me and Silvanus and Timothy, was not yea and nay, but in him is yea. 20For how many soever be the promises of God, in him is the yea: wherefore also through him is the Amen, unto the glory of God through us. 21Now he that establisheth us with you in Christ, and anointed us, is God; 22who also sealed us, and gave us the earnest of the Spirit in our hearts.
