2 Corinthians 1:22-24

22 set his seal of ownership on us, and put his Spirit in our hearts as a deposit, guaranteeing what is to come.

23 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.

24 Not that we lord it over your faith, but we work with you for your joy, because it is by faith you stand firm.
