2 Corinthians 1:22-23

He knows we are his since he has also stamped his seal of love over our hearts and has given us the Holy Spirit like an engagement ring is given to a bride—a down payment of the blessings to come! Now, I call upon this faithful God as a witness against me if I’m not telling you the absolute truth. It was because I hold you in my heart that I decided not to return to Corinth, in order to spare you the humiliation of my rebuke.
