2 Corinthians 1:18-22

18 But as God is faithful, our message to you isn't both yes and no.
19 God's Son, Jesus Christ, is the one who was preached among you by us—through me, Silvanus, and Timothy—he wasn't yes and no. In him it is always yes.
20 All of God's promises have their yes in him. That is why we say Amen through him to the glory of God.
21 God is the one who establishes us with you in Christ and who anointed us.
22 God also sealed us and gave the Spirit as a down payment in our hearts.
