2 Corinthians 1:21-24

Now it is God who makes both us and you stand firm in Christ. He anointed us, set his seal of ownership on us, and put his Spirit in our hearts as a deposit, guaranteeing what is to come. I call God as my witness—and I stake my life on it—that it was in order to spare you that I did not return to Corinth. Not that we lord it over your faith, but we work with you for your joy, because it is by faith you stand firm.
